wHATS WRONG WITH ME?? ADD/SOMTHING ELSE?

I cant get my life together/ I cant work out if I am just different and shouls be leading a different way of life because the ways of society doesnt really sit well with me....

I think I have some mental problems

I am bright, but pursued something creative..which after constantly comparing myself to others and always puttuing myself down.. I didnt do very well..I dont understand how to fit into the work world.. or to co operate with others..keep to a certain time or structure

I cant hold down a job.. I change my mind constantly! and relashionships for this matter have not worked out. I speand alot of time in my own head
I met one guy last year who i felt for the first time in 24 years that i could relate to... but i started being really mena to him/really mean...always analyzing everything.. worried what other thought of him.paranoid he was with other girls...picking out all his bad parts. which i tend to do AND I HATE THAT and pushed him away/ to the point when i finally told him how i felt he was over it.
now i feel like i loved him..and i cant get him away from my head. i dont understand my brain.

I dont know what I want... Or I do but it is buried in all these fears and worries.
i get fristrated with modernlife..things bug me easily loud noises. horrible places etc

my mind thinks about 10 things at once i have the concentration span of a fly...
i start things and never finish them... i never do chores...
i feel like a mess...

i daydream alot..
the reason i am now seeking help is because tutors on a teaching course i took said i may have add or dyslexia or soemthing else...
they said i dont have a logical brain..AND I DONT
so basically i need to find something that my brain is going to do well at... because right now I am crashing on a friends sofa... working out what the hell to do next and laso feeling low because i cant seem to find any direction.. thats all i want

i want to feel peace in my mind and stop constantly analyzing peoples intentions.. which path to take and the future i just want to enjoy life without this weird block that i constatly have in my brain...

since a litte girl ive ben odd.. always walking off alone/wanting to be alone, like now i went travelling alone for 9 months kind of to feel invisable...and now because of all that time alone..thinking and thinking and thinking,,, I am bored of spending time alone. I feel like i nee dto DO SOMETHING

i spend alotof time alone..but have LOTS OF FRIENDS i am attractive and people have told me they find it hard to approach me. but say i am the funniest and nicest persron when they get to know me.. andi think people would be shocked to know that i am frustrated in my head 24/7..sometimes i just cant even sleep and walke up with an empty feeling in my soul. I just want to get on with life.. but i cant do it....
