Getting anxious to go out!!!

So i had a csection last week Thursday 8/4 I was prehypertension and felt very faint and dizzy. They decided to deliver me at exactly 37 weeks. I had my staples take out yesterday a week later and went to the store didn't walk more than 40steps and I felt terrible like a burning sensation I hurt myself getting off the chair at the store literally sat the whole time my husband picked out some shoes for our oldest who starts school next week.
