do i have a mental disorder, what is this?

Background info: I am 23, i have had OCD since age 9, but no other health probs.

So i feel like something is wrong with me, mostly that i change my mind all the time, or everythings always in flux, i have a shopping problem, but it only bothers me somedays, other days i refuse to spend any money, everything is black and white it seems and if somebody double crosses me once they are on my avoid list forever, and i change jobs a lot. i have had sixteen jobs.the prob with jobs is i get restless, wonder why i am even there? or somebody double crosses me or says something and i turn into a baby. Somedays i feel i have the emotional ability of a 5 year old, i forget how to do a lot of stuff, and other days i am on top of my game, doing great etc.

everyhing is always chaning. somedays i dress punk other days it is hippie or preppy designer, i just feel like there is no consistency in my life. i always changed my major in school but now i have 3 degrees due to the fact that i am constantly taking random classes and getting involved with certifications and such.

there are some things that stay the same with me but it is really hard on my relationships. particularly my significant other some days i have zip interest in him other days im obsessed.

the big thing that got me to ask is something wrong with me,.... is that i keep forgetting stuff. i forget people, places, have gaps in my mind on memories. its weird.

i just want to know what do you guys think this is??? maybe nothing?
