I know I swing every day from counting my blessings to panic to anger to counting my blessings again.
I'm so sorry about your friend, Wayne. Sending light to him and you too.
It was hard from your OP to see where you were coming from. I'm sorry I wasn't more compassionate -- it wasn't meant that way. I understand getting tired of living in chaos. Just remember that will be temporary and you will have a nice bathroom when it's all over.
If your husband isn't the primary bread winner then he has no right at all to tell you what car you can get. Just figure out the costs of the replacement car you want and do it. Don't forget to factor in increased insurance and fees when you are car shopping. Another option might be to lease for a while (something I think about if mine gives out).
There are no jobs anywhere for those of us of a certain age. At 64, you can apply for social security if you aren't already collecting. It will be less than if you hold out until 66, but it's worth looking into.
If you do that, once you have a base income maybe you can start a side business. Teaching a useful hobby, or bookkeeping for small businesses or something like that? (These are just things I toss around in my head while I have so much time off right now.)
