Physical therapy

Okay, so I’m supposed to go to pt today, but I haven’t been doing my exercises. I feel really anxious because I can’t seem to get on track with it. Should I skip the appointment, do my exercises until my next appointment and never tell the physical therapist I skipped some days, or should I bite the bullet and go and have her thinking I’m a big fat loser? I could take 2mg ativan and not even care what she thinks and just go so I can get back on track. I’m so confused. I really don’t want to go. But it’s for my own good. What do I do?
