Welcome to the Healing Well Depression Forum, we are pleased you found us and we will try and help you as much as we can, we are all really good listeners on this site.
I think you need to visit your doctor and tell him exactly what is wrong with you, you may need some meds to get you past what you are going through and maybe you should ask him to refer you to a counsellor. I know money is an issue, but perhaps your Human Services Dept could help you. (I am guessing as I don't live in the US).
To me, you sound like you have lost all your self esteem and of course you have good reason, with the little bit that I know about
you, I think losing your job would surely knock your self esteem. Have you tried employment agencies, or just putting yourself out there, door knocking so to speak. I know your economy is still recovering and the job market is pretty tight, but once you feel well again maybe that is worth a try.
Everything seems worse when you haven't slept properly for days, which is probably why you and your mother are bickering. She is probably deeply worried about
you as well. You will be able to take care of yourself, you just need some help right now.
Please feel free to share more with us if you feel up to it, nobody wants to pry into your personal stuff but if you want to unload more of what is troubling you then I just want you to know that I am here and I am sure the other good souls on here will also offer their help and support to you.
So Jen, please keep posting, see if you can get to a doctor and counsellor and let us know how you are going. Remember you are not alone here.
