I can relate.I STARTED with acne at age 27.And I don't just mean the occasional pimple.I was having huge cysts all over that were very painful.
It got so bad at one point I did not leave my house for 8 months unless I absolutely HAD to.NO ONE was really sympathetic to my problem at all and kept pressuring me to go do this and do that.No one understood why I was so sad.Everyone around me had clear,perfect skin.And at my age I felt like a total failure.
Then I finally found a good dermatologist who listened to me and really helped me.I went to one before him that I paid 150 dollars to see (no insurance) who just sent me home saying to wash my face more!
My good dermatologist got my acne under control.I had a few relapses,but he always knew what to do about it.
Minocycline was one of the first things he put me on with differin and neostrata face wash,and it cleared me right up.
Also,Try reading this book called HEALING ADULT ACNE by Richard Fried.It helped me a lot when I was down, and addresses the emotional side of acne as well as the physical side.
(one final note: I think cigarette smoking had a lot to do with my break outs.I finally quit two years ago and my skin looks soooooo much better! Avoid any kind of smoke if you can,it is really bad for skin
