My flatmate recently informed me I have the emotional capability of a 4 year old and naturally I havent been able to get it out of my head.

I thinks it irks me because I've always prided myself on being mature for my age, which I genuinely am in other ways, but emotionally I'd say he was probably right. 

I dont know if I'm just upset that he noticed or upset that it's the case but I'd love to rectify the issue. 

I do struggle emotionally as well all do here, any criticism I receive tends to damage my self-worth and can send me into a spiral. 

Any tips on how to grow up? I'm 24 and would love to be there on an emotional level also.
