Joined a gym today

In 2016 I was in a car accident that almost killed me.  My husband,  who was driving, didn't make it.  I lost most of my right foot and all of my right femer. I was told after waking from a coma that I should come to terms with the fact that I would probably never walk again.  I gained a gross amount of weight in my two years in the hospital.  As of now,  I am down from 350 lbs to 125 lbs. I lost a lot of muscle and I have mostly been walking and exercising without weights.  Today,  I joined a gym and started using light weights for the first time since my accident.
