Gastric Bypass Cost

I am really considering Gastric bypass I just have some problems. First of all, I guess its best to let you know I am 6ft and 335lbs. male and I am 20yrs. old also I live in N.J.. I know this is severely overweight and morbidly obese. I am a full time student I also work full time. I am still covered under my dads insurance (cigna) which I believe has some type of gastric bypass coverage(not totally sure). What am trying to find out is how to tell my parents that I want to get this done I am afraid of it being shot down and dismissed as just a fad or phase. I already got 1 back surgery under my belt, and my back is only gonna get worse if I stay at this weight, my health can only get worse. Besides that how much is it gonna cost (with and without insurance). What are the after cost? I know there are many different procedures which one would be best for me? What major life changes will I have to make after the surgery? um….. If you can think of something else I should know plz comment
thx
