And I want to add that recovery for me has been like 2 steps forward 1 step back the whole time, when I think I am feeling all good, I am, but I can't push myself too hard or I will feel worse again for a few days or a week. It is a fine balance between doing a little more than say last week, and doing too much, which takes some time to get the hang of.
Be kind to yourself, you have injured your brain, which is, as you know, very important to you, and your body needs this time to heal. If I were you I would put the surgery on ice for now, if you schedule a new appointment you may feel stressed and pressured to get well by then, and that stress will just make you worse! If you push yourself into doing your operation you might just end up getting worse after your surgery and if you feel like crap you won't care about your chest size anyways... I don't want to tell you what to do, you do what feels best, just try not to push yourself too much, it will pay off in the long run taking it slow!
