I have two pieces of advice for you:
1st - MOVE OUT OF THE HOUSE! I had a similar situation to your when I was in my early twenties. I have situational stress and that caused a portion of my acne. My mother was always screaming and yelling about something. We could not communicate properly with one another. Until I moved out I didn't realize what a weight was lifted off my shoulders and my face started to clear gradually, not entirely though. I will never EVER move back into that house again because we have different lifestyles. What that meant for me was I was determined to find any means necessary to survive. Live with friends. Find a really cheap apartment. Live with relatives. Whatever it takes.
2nd - GO FIND A JOB! Don't let your acne become the reason you become introverted. I work in sales believe it or not. I face the public everyday with acne and still do my job. Most decent human beings will not judge you. I work mostly on enthusiasm. That's what gets me my sales. I have trained many young individuals with acne worse than mine that still go out and try their best. Whenever I feel depressed from my acne I think about all the people that would be lucky to be in my position. That humbles me greatly. I know that there are people with disabilities that are far greater than mine that still cope with everyday life knowing that they will not have all of life's opportunities. I have a roof over my head, clothes on my body and food in my stomach. Sometimes when things are going bad in our lives it clouds our judgement to make good decisions and be appreciative about what we do have.
Hopefully you can find a resolve quickly to your situation. For me moving out was the best thing I have ever done. What works for you may not work for me and vice versa but we are all communicating about it and that is a step forward. If you ever feel like talking more don't hesitate to message me. We are all in this for the long haul.
