I want to be happy.

Hey ladies, so I have GAD (Generalized Anxiety Disorder) which I've worked with a counselor to determine that it stems mostly from a need for acceptance. In other words, I consistently worry what other people think of me, how I am perceived, how my actions are looked upon from the outside...basically everything to do with that. It's pretty severe to the point where I cannot be happy with myself if I have any negative feedback from the outside world. It's detrimental because obviously there's no way to make everyone happy, leaving me consistently unhappy. I usually see a counselor provided to me by my university, but since school isn't in session, I haven't seen her in about a month. I'm exhausted by my own habits and I just want to be better. Any advice?
