Is ok to feel this way? or do I need a slap in the face?

I been dating my boyfriend for more than 10 months I adore him I love him but since at 8 months I can't feel like I am needed as I used to be or reach to him as other can, he has some social anxiety issues I knew this at the start cause a chick that screwed him over I helped pick up the pieces before he dated me when got depressed ( i suffered depression in the past and social anxiety issues my self was able to help him and I was the second or first person to go to and now I feel like I cant cheer him up like I used to, for a couple months my shifts gone up from 3 days a week to 5 shifts doing 40 hrs a week come home always buggered but since I don't live with him and he wants me to move in next month but one his best friends girl friend has been helping him cope while I am work I know she adore her boyfriend so no jealously but I feel replaced I went to the movies with her and her boyfriend and my bf was sitting next to her and I was on the end I felt cut off most the movie cause her and my bf cracked alot of jokes I used to make my bf laugh alot I feel useless I guess and my best friend has a child she is busy and I understand that but she was worried about me too cause I work alot and I am always exhausted now, I always been attract to smart men but sometimes when I ask a question about something seems kinda dumb but I couldn't understand he acts bit condescending when he answers I feel so dumb and useless cause it was a computer question I love him and he was drunk last night I was there he kissed the friend on the forehead that been helping him cope it bugged me a little but I was drunk so perhaps I took it a negative response he says he sees her like a sister but I feel like I am not good enough to help him he never runs to me much for help I love helping people but I guess I don't feel needed I feel so foolish to feel this way cause the past week been crying my self to sleep I feel lonelier and disconnected I do my job well I guess out side I am just useless
