I’m trying to lose weight after spinal fusion and disk replacement

I had a rough road. In and out of hospital for a few years. A little over a year ago I had a spinal fusion and disk replacement. I had to take meds that due to its side effects it made me gain weight. I lost hope, motivation and discipline. I thought it would be impossible to get to how I used to be. (I use to be an athlete in calisthenics, parkour, boxing and skateboarding but I lost all my strength) now I'm trying really hard to get back into shape and meet myself where I'm at. I'm too embarrassed right now to post a pic of me working out 😢 (hopefully that will change soon)
