I'm 24yo F. (Undiagnosed BPD) And I've been struggling my whole life with trying to figure out who i am or what I like because I always end up liking what others like!!! Or trying to fit in everywhere... 

I get so lost and so exhausted of thinking what am I, what do I want/like. It depressed me because I see everyone else being so truth to themselves, sticking to their own ideals but with me changes every minute (every minute)...

...I just would like to know what works for any of you, how can I keep myself in my own line.  I hope this makes sense.  
 Thanks
