I am terrified there is something really wrong with me, a brain tumor or early onset dementia or the like. Also, I have stomach problems which have been causing me anxiety. I was diagnosed with gastritis in August, and have been having a lot of those symptoms the past couple weeks (nausea, feeling full, lack of appetite), so it seems to be acting up -- I am trying to convince myself that given my past diagnosis, this is unlikely to be cancer and I probably just wasn't careful enough with caffeine, alcohol, etc. before.

But also, I have noticed the past week or so I have been making strange mistakes that are unlike me. My partner was doing pullups and I couldn't remember the word for them, then I freaked out. I've had trouble remembering little things -- names of restaurants, streets...usually I'm good with that sort of stuff. I'm meeting a friend for dinner tonight, and completely mixed up what train I should take, I know the area really well and this is a strange thing to mix up for me. I also am supposed to meet her at 8, but was planning the evening around leaving at 8 to meet her -- another odd mistake not typical for me, I'm usually very organized and together. I am really stressed about the stomach stuff, and now about this, so I hope my lack of attention/preoccupation/anxiety is simply the cause of all of these weird things, but I'm really scared I have a brain tumor or something (particularly combined with some twitching in my finger and eye I've been experiencing) and my anxiety is spiraling out of control. Any advice would help a lot.
