Not having the right mentality to succeed

Note this isn't a post born out of frustration and I am not a frustrated kid who is pissed he could not get a job.

I am grateful to have had a lot of success in life but I am wondering at what cost.

The more things I get involved in the more I realize that I don't have the mentality to succeed.
I used to suffer from severe anxiety which I have now managed. I also suffer from mild paranoia and I just sometimes get so tense.

It is now managed but certain stresses and situations become a trigger. I struggle in new situations. I know I am triggered when I can not shut my mind off.
Something I have found out about myself recently is that I don't accurately see the world. I see the world through my emotions rather than what actually happened. As a result I am very clueless in situations.

I have mild learning difficulties and I just scrapped through school and Uni.

I feel like I would be much happier in a random low paid job.
