Your "therapy hangover" is normal. That is what therapy is supposed to do- shake things up. make you feel things that you have been avoiding letting yourself feel so that you can "process" or "deal" with t he situations and therapists call it. Basically. People get therapy for a problem- they pay a professional to listen to them and make them think about the situation from all angles so that the person can solve their own problems and make themselves feel better by not being so upset by them. Weird I know to feel better sometimes the person has to feel worse. The reason they feel worse is because the person is no longer shutting off their feelings. Instead of shutting out and off the person who is in therapy is learning different ways to take care of ther problems other than shutting out and off. Bottom line you are supposed to feel.
