Welcome to the Forum, Lillian.
Have you told those around you that you need some help and support? Sometimes, yes we do have to, shout it from the rooftop so to speak, as people around us may not notice, especially if you are what is considered "high functioning", and where you are taking care of someone else, sometimes people forget the needs of the carer.
If you haven't told them any of the caring people around you, maybe you can start there. I would only imagine that their care and concern would extend to you also.
Are you unable to get to a doctor even for one visit to discuss how you feel? Does your husband have any doctor visits? If so, could you mention it to his doctor the next time? Are there any free or sliding scale resources around you?
If not, please also look into alternative or OTC treatments to see if they can assist for a start even. Sometimes we have to do "something" for a start, even if it is not the ideal way, it's worth a try.
I'm glad you found us here; I hope we can be of some support to you.
