I would suggest calling The Patient Advocacy Foundation. I'm a cancer survivor & have had jobs where I'm the "advocate" for others. What I like about this place is they will ask your questions about what your situation is & match up any resources from other organizations that may be helpful to you. It's rather like a "one-stop-shop". You can find multiple contacts for resources with just them.
Caregivers absolutely need support and it's not just about food, of course. Though, as a WLS person, I understand that one too.
You might not find a forum for WLS people who are also caregivers, but you can get more resources to help so that you have a little more peace of mind that things are getting taken care of when you need to take some time for yourself - which you do! There's nothing wrong with that!
I would also suggest that you find a caregiver support group in your local area. I'm sure there are others who struggle with turning to food, or ciggies, or alcohol during these times also.
