Struggling

I am 8 years post op and I am having some complications I think that may be related to surgery. Wanted to get some advice. First a recap, I was 358 lbs and lost as much as 225 lbs but gained 75 back so I am sitting at about 220lbs now. Of course I am not happy with that but I am trying to get back on track. My issues are that regardless of what I eat I feel nasea after and a need to lie day till it passes (usually and hour). I am afraid to eat much of anything these days.

Anyone else struggle with this? My doctor passed away so I need to find a new doctor soon.
