I've found the OU to be brilliant. My tutors for both my level 1 modules were both incredibly supportive and had no problems giving me extensions if I needed them when my head wasn't working properly. It also removes the need to leave the house and actually deal with people!!!

Breaking down with a counsellor/doctor is ok. They've seen/heard it all before. They'll be able to suggest services that can help woth self-esteem too.
