Depression is a clinical diagnosis and largely specific to brain neurochemistry, it is not being pissed at being screwed by your company.
Clinical depression: What does that mean? - Mayo Clinic
Be careful about acquiring a diagnosis that is not real. Once it's in your record, it's in your record and you can squawk all you want, it's not coming out. If you've never been depressed it's unlikely your going to develop it now. As you work through this your mood will likely improve. OTOH if it persists then go get a diagnosis. Keep a weekly log of how you are doing because you will tend to forget and it's worth being able to review. You are
not qualified to diagnosis yourself. I lost my big deal job when I was 58, back in 2010. I temporized with another job at half the dough for another 7 years. I mostly took the second job for health care since my kids were in jr high at the time, so healthcare for my family was the boundary for me on ER. Work it like an engineering problem, boundaries and process efficiency.
You already have saved the majority of what you need. Every progressive year will yield less and less effect on the long term prospect of your portfolio's survival. Go to SS and get a listing of your earning history, and play with the numbers. See what 7 years of 40K per year v 7 years of 80K per year (or whatever) does to your lifetime aggregate earnings. It won't make much difference, but prove it to yourself.
Personally I would be concerned about a 800K property with those taxes. It's not hard to sell in good times but in bad times when you need the dough selling a property like that can turn into a career. When I moved to this town I looked at some high end properties. Some of those sellers still hadn't sold 2-3 years later and they were calling me up begging me to make them an offer. That is the problem with "dream homes". They are your dream but may not be anyone else's. You can do the "what-if" on that too.
For Medical care my wife is still far from Medicare and I have 2 kids in college so I need it. We did a concierge plan with a primary care doc plus a major medical called Liberty Healtshare. It's $399 per month for my wife and 2 kids, ACA complaint, and low deductible $500 per person. I combine this with a HSA So that's something you can look into. It takes a while to get all the moving parts moving again is all.
Do not be discouraged. To be discouraged literally means to be without courage. No future in being without courage. As Jerry Garcia said "I will get by, I will survive.." Pretty soon you'll be all retired sitting around on your sun porch drooling in your lap (like me).
