I have the same problems from mold exposure. I can't go into any environment where mold may be an issue, like thrift stores. My stomach issues are getting worse as well. It is possible that continued exposure is just making these reactions worse.
I got a lot better initially after I put all of my belongings that were exposed in storage. I have been going through and moving some of these things recently and sure enough, I'm feeling more and more symptomatic by the day, especially with gut issues and not being able to eat anything without it hurting. Also having really bad sinus mucus and pain, depression, mood swings, fatigue etc.
Just trying to get rid of a lifetime of things is killing me. I don't care about the stuff anymore, I just don't want to feel so sick like I did after the initial exposure about two years ago.
