Need life and job advice - breaking in to financial services/ trading

Hi, I am wonder if anyone here who have experiences in the financial service sector give me some advice if the career path is feasible or logical. Sorry if my English isn't perfect, as sometimes I find it hard to express myself in word.

About myself
I am currently approach 30 soon, I am an introvert. My personality is often slightly social awkward and shy, but very friendly once I become close with people I trust. I live in New York City. I won't say I'm the brightest person, but I am outgoing and tamed. Often I will have strong commitment when I find something I am really interested in, you can say things like competitive video games, and certain types of sports. I will figure new tactics to get to first place.

However the reason that I am starting this post is that I have been frustrated with myself and my career path, I wish I figured out sooner about what I wanted to do in life. I graduated with a degree in economics at a government subsidized college. While in college I didn't take any actual finance course until the late years. Once I learned about the financial market, I've been obsessed with trading and investing ever since.

The dilemma was, when I graduated this was around 2013, when we were still coming out of a recession, I struggled to even get an internship. After a year of mulling around and trying to co-start some small business with college friend, it lead to nowhere. I finally landed some temp finance job because I was desperate as a undergraduate and no job, but I have since been working different entry level finance job. Fast forward couple of years of working in the back office finance and I am currently a Financial Analyst, I feel ashamed because I thought this was a great career path that I would enjoy and is manageable for me and in moving up the rank. However after having the realization that I was working in the backend billing side (Accounts payable, billing, headcount and cost analysis) I realized this was not the type of career I wanted to be doing for the next 30 years. I don't feel like I achieved much making 55k in an expensive city and I am approaching 30. It had even reduced my confidence and don't even know how I am even able to save up money to raise a family with that salary. I don't even know how long it will take for me to move up the rank to hopefully get better pay as a senior financial analyst. Because I didn't start my career path in the accounting side, I felt like it slowed down my career progression significantly. The job is not difficult but I feel like I can do more in my life, I like working with excel, but in terms of my job responsibilities it is very mundane and mind numbing processing invoices and tracking cost, when its not my interest.

If only I knew sooner that I should be looking for jobs that are at least in the front end revenue generating. It is sad to see one of my friend who we both graduated at the same time, he is currently a manager making well over 100k in the marketing advertising field. I know we shouldn't compare, and I should find something I enjoy doing.

I always had a craving to learn more about the financial services industry and get a job in the field, but there is always this fear holding me back, because I came from a B/C rated school. I didn't come from top tier Ivy league, and it's very intimidating and degrading that recruiter and large institution always look at those candidates before I will even get a glance. I have tried applying for junior trader and financial market jobs, but I never yield success or even an interview. So I gave up and continue doing my current job type.

Most of my free time for the last few years was spent trying to teach myself to learn about investing and trading in the stock markets and options trading, and try to gain financial freedom. I knew the odds were against me greatly in a asymmetrical game but I still went and did it. I went thru all the possible mistake an amateur could make in trading. I made some and lost some, but for the most part lost money. However I still enjoy the game and, it became a growing obsession continues to this day, I have strong passion to figure out the financial market. I have self taught myself to look at charts, market structure, risk management structure, options pricing, volatility, price action micro structure, and nuances of order execution/ layering on risk, price discrepancy, etc.

Although I don't have the knowledge of a quant or investment analyst at a bank, I really want to work in the financial markets sector ever since I learned about it. It is frustrating to the point that even at my job I look at the stock markets and run analysis while doing my own real back office finance job. It is messing with my head, because if I commit so much energy and passion to figure out this stock market, I always ask myself why am I not working in the financial service sector. I know I'm not the smartest math genius, but I have fears and regrets that I never got a chance to try out to work in the financial service as a junior trader or some job at a hedge fund.

Do you think I even have a remote chance at this age and experiences, as I am not very experience and never worked in the financial services sector. What type of job would fit my personality or interest. Do the type of jobs even mirror to what I am interested in terms of job responsibility? Should I just stick to my current career progression.

The irony of it all was I wish someone told me about stocks or investing when I was growing up, I would had found my passion earlier in life and go for it rather than later. Sorry if I am rambling, I am trying to get the words out from deep within me. I couldn't find any other way to type this out in the middle of the night.
