To be honest, the OP could benefit from counseling. So I can agree with you on that. Being under the guidance of a licensed Psychologist could give him that extra push to get out there and feel like an adult rather than someone living under their parents roof passing time in a depressive state.
My issue was with the way you carelessly threw him that diagnosis of Avoidant Personality disorder. Firstly, the Diagnostic and Statistical Manual (The DSM) which mental health professionals use to diagnose patients, is a debated document in the mental health community, one which I don't particularly agree with. An armchair psychologist online telling others that they might have a certain diagnosis can cause undue harm on an individual as many times a diagnosis leads to a person feeling trapped and helpless inside a box based on the determination of another human being. Many mental health professionals these days are reforming the profession instead focusing on symptom based treatment. The profession in the last 4 decades has been rather obsessed with encompassing labels created by a panel of wealthy psychiatric insiders who votes over cigars and martinis at a 2 day conference at the Marriott each year.
My point was that someone suffering from bad acne who is afraid to go out is not a typical avoidant personality. Avoidant personalities usually suffer from a delusional way of thinking about others based on judgements they project onto others. Their delusions are based on traumas, unfounded and distorted logic, but almost always based on a low self worth.
The OP's issue with going out into the world is more of an agoraphobia stemming from on a medical issue that results in a socially undesirable physical appearance. Yes, physical and mental health go hand and hand...but a true avoidant personality would not be someone who is avoiding college because they have inflamed lesions on their face. It would be based on their disorted and overblown misconceptions about others. I think its safe to say in our appearance obsessed society someone with bad acne is likely to be judged and possibly made fun of by others. There is a good chance they will suffer socially and miss out on job opportunities, events, dating etc as a result of their appearance. So OP's low self esteem and fear of rejection is not based on a delusional fear of others, it is based around how individuals in our culture, particularly 20 somethings, view people with severe acne.
But as someone educated in human behavior, and as an acne sufferer, I must say it is unwise for anyone on an internet forum to tell a complete stranger that they have a specific psychiatric diagnosis. However I think you may have misspoke, so don't think I am calling your character out...just your choice of words.
Moving along to what you asked about disorders, as you may call them, such as PTSD, are really just clusters of symptoms in the DSM that cause someone difficulty in coping with life (they range widely in severity so my description was over simplified). Now, PTSD may be related to a past physical trauma, but personality disorders are not typically related to someone suffering from self esteem issues due to a physical deformity. If OP's type of issue was to be diagnosed it would probably be Social Anxiety Disorder NOS (Not otherwise specified) but I honestly think most mental health professionals would avoid diagnosis as OP's anxieties are perfectly normal in the circumstance.
I think it would be a good idea for everyone on internet forums to put the psychiatric jargon down for a second and let professionals make these determinations. Right now, we should focus on the OP at hand. He is suffering and in need of a push into a type of lifestyle that meets him halfway between being totally uncomfortable and safely isolated. This way he is doing something and is productive member of society, despite his condition which I hope he finds a solution for. Hope I was some help.
