I FEEL I'M LIVING ON BORROWED TIME

I'm from Australia but live here in the US.I have no family or friends & I'm divorced.I never talk to anyone.I avoid answering my phone as I don't have anything to talk about.I can't find a job & I have severe anxiety,depression & feel like I am failing miserably.The stress & worry I have from no job & watching every penny is having an effect on my son.He lives with me weekdays & with his dad on weekends.Although I try to hide it,he knows I am overwhelmed.I would never consider taking my own life but I feel that this will become so bad it will take my life.I suffered a seizure in my car last year.It was stress related.Thank God my son wasn't with me.I just want to live & be happy the way I used to be.I hate the way I feel & it's getting worse.I think about the things I want to accomplish but when the time comes around, I can't find the will or the energy to do anything. I used to be so happy & outgoing.Now I avoid talking to anyone.It's Thursday & I have not left the house since last Saturday.I just want my life back.I know so many people feel the same way.If I don't get better,I am terrified of living the rest of my life this way or that I won't be able to function as I barely eat anything due to anxiety & one day my mind & body will say "I've had enough".This truly is a real issue many of us have & isn't easy to get away from it.I sincerely hope that all of you and myself, can beat this some day.
