*idk how to properly describe this so excuse the childish explanation*
I'm unable to have a solid and consistent opinion, goal or thought.
You know how people want to have a relaxing job or have a job which makes a lot of money or one which contains a lot of action.
Or when it comes to family. They want a boyfriend and then husband from life with kids while someone else would rather spend their time hooking up.

Ofc people aren't 100% certain but they have a general opinion or want or thought about certain aspects of life.

I feel like I go thru 5+ different opinions or goals thru out the day. And each time, I feel like that thought or opinion is one I've had for such a long time and I'm sure that that's what I want from life. But then a few hours later, it completes flips to something else. As if  a different someine was in the drivers seat making the decisions every time

That's driving me insane! Especially since it ruins any and all relationships or friendships I make. Or attempts at studies or jobs

A way I look at it is... My brain is a game. And I've got different worlds/saves for the game. Each one completely different. With a different goal, different wants and needs and different opinions and thoughts.
And I go thru like 5-20 different worlds a day.
I would like say that I am aware that I am 1 person. I don't talk differently or dress differently because of those shifts. 

So yea idk what to do. The only thing that seems to be helping even a little bit is quetiapine (prescribed). 
But this behavior is ruining my life and I feel stuck. I don't think I'll be able to deal with this for much longer. This just isn't a life worth living if this doesn't change
