I will literally go to any extreme just to recieve praise or happiness from people. Like not sympathy bc personally it makes me uncomfortable but i crave validation and positive praise. Like I will shift my entire personality just so someone will think im so cool or amazing even though I know deep down im worthless and not really that amazing. I just love hearing it from other people because maybe i can make an image of myself to others that is actually desirable and positive instead of the version of me that i know that is so annoying and bad. When in was in highschool i would lie about grades just so my mother would be proud of me and praise me for doing well. i will lie to my therapists and family ab how good im doing so they praise me and say im doing a good job. 
how do i stop doing this? it's exhausting almost needing to think of ways to get positive feedback from people.
