I urgently need some advice and help for IB.

Hi people of WSO. I know this is a long shot, but I wanted to write an intro to my story. I am currently a junior at a non target college with a GPA of 2.6/4.0. Before anyone starts telling me that I'll never make it into IB, I just want to say that I've finally come to an epiphany several months ago. When I was about to enter high school, my parents had forced me to enter into a finance magnet program. In high school, I did not know what career path I should take and what I wanted to be. I know many of you have had IB in your mind since high school and the beginning of college but I know I am very late. I had learned the basics of accounting, finance, and marketing throughout high school and passed with a advanced honors diploma and a weighted GPA of 4.1 / 4.8 and a unweighted GPA of 3.3 / 4.0.
Now this is the where the bad part of my life begins. I decided to go to a state college because my parents were not very wealthy and did not have have the money or funds to help me pay for a more expensive school. I know I'm very dumb for messing around in college and not taking it seriously. I went through two years of college not knowing what I should do within that time. I completely regret it now and wish I had looked into investment banking while I was in high school. The problem is that I am in my second semester as a junior now and have obtained a GPA of a 2.6/4.0. I know this is absolutely terrible but I really didn't know what I wanted to do in life. Until 6 months ago, I started doing research on the many divisions of IB such as Sales & Trading, Investment Research, Corporate Banking, and Investment Banking internships. I had messed around too much in my first 2 years of college and only now have I realized I want to get into IB.
You may ask why I want to get into IB. I'm not going to bullshit any of you and I'll give you my real reason. I first wanted to get into investment banking because I saw the average salaries of the many analysts and associates that make six figure salaries coming out of their undergrad and MBA. This had excited me a lot because I really wanted to make money. Coming from a lower class to mid class family, I had to deal with a lot of life issues that dealt with money. My parents had always been careful with spending their money. I had been eating mostly only rice and vegetables for over 13 years now. My parents rarely go out to restaurants because they are too expensive. The reason why I was so interested in making a six figure salary was because I want to make my parents happy and give them as much money as I can provide to them. I had always thought money can't buy happiness, but I've lived a very dreadful life where money has always been an issue. Six months ago, I started doing a lot of research on investment banking and reading hundreds of forums on WSO and mergers and inquisitions. I have started to step my game up and have been reading many investment books on my spare time and self developing myself as a person. Now I know many of you may call me stupid and dumb, but I WANT to break into IB. I want to learn about the fundamentals of Sales & Trading and Investment Research. I am very passionate about breaking into this career and I will do anything to learn and become the best.
Anyway, I wanted to share with all of you my experiences so far in my life. In my first year of college, I worked two jobs during the summer as a back stock person. I worked at Nordstrom and Abercrombie at the same time and had learned a lot about the retail business. I know retail will have no effect on my resume but I honestly did not know what to do my freshman year. My second year of college, I spent my summer working at a real estate property management firm. During this job, I showed hundreds of people properties that my firm was renting out, and I spent a lot of time in the office marketing out the properties online. Again, I know this will have no impact on my resume but it is some of the only work experience I have. It wasn't until recently that I started reading that I should have got finance experience in my first and second year of college. I still deeply regret not looking into a career path before I decided to go to college.
So my question to all of you at WSO, I want to know if I can still get into or break into IB. I am very passionate and willing to learn right now. I recently obtained a financial adviser mentor and have been reading a lot of financial management and investment books. I do not want to give up on this career, but I know it is very very slim for me to even get an analyst career. WSO has been an amazing place where I have learned a lot about IB and the financial industry. Since I am a junior in college right now with a bad GPA at a non target school, should I go through one more year of college and try applying for IB again next year? I have already applied to many IB everywhere such as Barclays, BOA, Citigroup, JP Morgan, Morgan Stanley, and many others. I know my chances are very slim but I still want to try my best. I have many questions as well. Should I apply for a financial based internship this summer if I don't get into any other internships? Should I go through another year of college so I can fix my GPA and try for another chance in IB? What should I do is my biggest question? Thank you very much to any of you who could help me out. I am very passionate about this path and I will do anything to get a shot at being a summer analyst.
