I'm sorry to hear this but I do understand. I was a teacher and teachers don't pay into social security...at least they didn't when I was working. I don't know how it is now. So, I have almost no points towards social security.
I left teaching many years ago to raise my family. My husband died suddenly and all of a sudden I had no health insurance. I have several other illnesses and no one would insure me. So, I was able to draw off my husbands social security and that's how I managed. It sounds like you are getting some from your husband, too.
There was a time I was thrilled if I had $35 left over after paying bills. My three children were young and a lot of money went for medication for me. It was a bad time but we made it through. I shopped at "generic" stores, went to garage sales for Christmas gifts, etc. Even though this isn't what I thought my life would be like, we still had a great life! By the way, if you have an Aldi's close by, check it out. There are a lot of things I buy from them and they are inexpensive, too!
Also, you might get in control of your pain and can re-enter the work force. I could work if I wasn't legally deaf. I have to lip read to understand speech so I can't really work in an office...can't hear on the phone. But, you could and if you find what helps you be in control of fibro, you will be able to jump back in the work force. I hope this happens for you. Meanwhile, we have had some members watch children after school, etc. Perhaps this is a means of adding some income for you. Just trying to think of things that could help you out.
I do understand your disappointment but there are better days ahead of you. Just plan on them!
God does not give us a spirit of fear, but of power and of love and of a sound mind. 2 Timothy 1:7
