Hey you! We missed ya!
Now that the niceties are out of the way, you have to go to pt!! You are allowing scar tissue to build up and cause the numbness that is only going to get worse for you. You have to remember, no one at pt care if you weigh a little extra or a lot extra, they are there to help people feel better and it isn't always the skinny minis that feel bad, in fact it is us heavier people that don't feel great because we are heavier than we should be. :) pt wont help you lose a ton of weight but it might inspire you to walk around the block until that becomes easy and then as you kick the walk around the block in the butt, you can go around 2xs and probably pt will help with the numbness too.
You really need to try to build up the courage to go that first time and see how they treat you, if you don't like it, don't go back. More than likly, you will see that they don't even bat an eye. Physical therapy isn't just for the little people but for everyone!
Write back soon and keep us posted,
