Every time I go to the gym...

Every time I go to the gym I remember the first day back at the gym. I was nervous just walking into the gym. The bright lights, the noise.... Being around people. I just wanted to go home to my comfort zone. I was encouraged by my husband to at least sit on a machine which I eventually did. 14mo.s later and I can now drive to the gym. I mostly swim because I am not comfortable on the machines and I still can't move my head a lot. I could move my head before the surgery, but now it makes me dizzy to look to the left for very long. I can look straight somewhat, my most comfortable position is to the right...
