I am really weak/unfit. I never was a sporty person, P.E. always was my worst subject, and since I've been out of school, not having to do any kind of sport (plus being sick for quite a long time, having to mostly lay in bed for months) I became extremely weak. I literally can't do one push up. I get out of breath after walking one flight of stairs. I would be okay with this, I'm slowly trying to become fitter for health reasons, but... the problem is that I am going to school again from now on. And there will be P.E. classes. And 20 people will witness me not being able to do one push up, run 2 minutes or throw a ball across a 5m field. I am so embarrassed about this, so afraid of the lessons. I try getting in shape faster, but with all the school work I have to do, I quite literally have no time for a proper training. It will be so shameful.
