i have 2 friends who both seem to have low self esteem/confidence and they both are always nostalgic about past memories and they both only talk about themselves and their problems. i get it they are having a hard time , im here i listen to them but it kinda sucks that they only talk to me when they have problems to talk about and i just feel annoyed but i dont want to feel annoyed because i want to help them i spent a lot of time not having anyone to talk to about my problems so i just want them to know im here but its difficult to listen to them if inside im feeling annoyed. help?
