I am going through the same thing.
I injured my knee about a year and a half ago. I am stuck in a knee brace waiting for the stupid doctors to call me back to schedule physical therapy or surgery.. anything.
I can hardly walk anymore.. it hurts sooo badly. and it's taking a big toll on my emotional health.
I have gained so much weight. I used to be little and now I'm like ..not so little. haha, and I'm soooo tired of it!!!
I hope things work out for you!!
Take care.
