First Tennis in about 6 months

Played tennis for the first time in 6 months yesterday. I was a little anxious about it because of the rapid heart rate, out of breathedness and exertion involved. Overall I think it went pretty well. I was hitting the ball well and I only felt maybe a level 6/10 anxiety at a few points. I know now that feeling that kind of anxiety is a good thing because it means I'm making progress. I had to take like 3 breaks to catch my breath, but I think that's more of an out-of-shape thing rather than an anxiety thing.
