Wow, it really sounds like you have a lot going on now. I think you have good reason to be feeling anxiety, and I'm pretty sure that can cause the belching. It's one of the few symptoms I don't ever seem to get -- I just rarely belch for whatever reason. But I've been around other people (family members/friends, etc.) who do seem to belch more when they're nervous, stressed, uptight, etc. Maybe this will all settle down once your life calms down a little bit.
