Rollerblading and overweight?

I am almost 20 and when i was younger I used to love to roller blade, and I was good, but I haven't done it in about 9 years because I moved to a rural area. Sense the time i last roller bladed and now I had reconstructive foot surgery basically to correct my flat feet, during the recovery I put on lots of weight and never burned it off and over the last 5 years its only gotten worse and now I am very over weight probably about 350 pounds. I want to try to roller blade again but last time I tried (3yrs ago) I couldn't do it anymore the biggest issue being weak ankles. So I am wondering if there are any suggestions on how to make it a little easier on myself at first and if there is any special skates I could try because of being over weight. Also I have very wide feet so being in skates that squish my feet for to long is unbearable. so any suggestions would really help
