What Causes Instability In Thoughts?

Ever since I can remember I've always changed my mind so much. Whether it's a relationship or a job, I become almost obsessed with an idea one day then next I have completely changed my mind. It's made it hard to keep a healthy relationship or keep a job. I feel like I have no direction in life because of it.

Not only do I change my mind often I also change my feelings and emotion all the time, In one day I could be angry then Happy, then sad, then optimistic, then hopeless... then usual It really puts me down.

I think I may be depressed slightly and anxious which I know would not help but this has been going on for years now.

It's made me have awful trust issues, and I find it hard to keep friendships because of it. I always think the grass is greener on the other side, and I over think everything. I feel like losing my mind !!!

Do I have dyslexia to would this effect it? Or is it a different problem please help all my life I've put myself into bad situations its like I like f**king up my life, or I like the drama ??! please help!
