Yep, I hear you on the big mess!! I'm an expert at tying myself up in knots! It's great you're back on the Zoloft though. I hope you're able to get back up to 200 mg soon and that you really notice the positive effects.
I'm on 100 mg daily. For some reason - and it's probably psychological - I can't seem to go above 100 mg per day without my anxiety symptoms worsening. My pdoc wanted me to increase to 200 mg daily and I didn't think I'd have a problem since I tolerate Zoloft well. I went up to 125 mg per day and on that day I had a terrible panic attack. It could well have been a complete coincidence, but unfortunately there's now a part of me that associates increasing my Zoloft dose with increased anxiety. I've tried increasing in minuscule amounts (1/4 of a 25 mg tab) but even that unsettles me. So I'm stuck at 100 mg per day (needless to say I'm scared to come off it just as much as I'm scared to increase it! So "stuck" really is the operative word!!!! )
I can relate totally to the health worries, specifically about cancer. My parents both had cancer and I feel like I'm next. I've had quite a few tests and they've been "normal", so I'm trying really hard not to obsess about this (but that's way easier said than done. Especially, as you say, since there is no test for cancer).
I really hope you get a positive response from the mortgage company and that you and your family can stay put. I'm so sorry for the stress that uncertainty must be causing you. I'm really sorry too about your job stress.
Keeping everything crossed for you that things improve
