How can i help him😫

My boyfriend has anxiety and thinks he’s depressed.

He doesn’t have many friends and a lot of people dislike him because of the things theyve heard about him.

He always says how lonely he feels and i reassure him and tell him to tell me all his problems and i’ll try to help etc.

Its hard tho. It stresses me out. I constantly have to think about making him happy instead of myself

Advice? Opinions? Help?
