You are in a crisis. (& I am anxious just reading it, it hits a little too close to home)
If you can; do get in touch with brother to see if (?there are jobs in the area, could you and daughter stay with him a few months to find a job and apt.?----) or same with a good friend. Or/AND, call your PCP if you have one you trust and make an appt., give him/her the post (before that tell them what you are looking for is "Where do I go to get help in this community? Where do I begin? and Would a med. help me feel calmer, less depressed while trying to get my life back together.) Have you applied for unemployment? With that, also, go to social service agency and find out about/apply for subsidized (or temporary) housing/food stamps etc.
This is a terrible situation. [How is daughter doing? She is young, but perhaps could get a part time job to help out and to help her cope also, she is used to you being the rock and it may be very hard for her to see you any other way, or to even 'believe' you can't manage it all like you always have]---use the local soup kitchen, food bank, Anything that will help feed you, cut expenses, get what you need.
I am so sorry, so so sorry...you are dealing with the results of things out of your control. Also, try to take on just one "deal with it" task a day, break it down and prioritize your needs and take it one at a time. Do reach out for any help you can get. Since you have not been "here" before, you might be better at this than some of us who have long term anxiety/panic/depression issues---this is situational, and your reactions are Normal given the situation. Keep posting...((((((hug)))))))
If you own things, sell them online or on consignment. If you own a house, consider selling, sorry-----------just throwing things out there.
