Need depression advice but am on a budget

I recently had to move back in with my parents because my hours where cut back at work. I lasted on saving until my lease was up, but I could not sustain my way of life on a lower salary for long. I still have a job for now but I am being paid less. I can’t do all the things I use to do like go to the movies. I feel embarrassed when people ask me to go out and I can’t afford to any more. I am looking for a new job, that pays more. However the process is exhausting and I have gotten to the point where it is hard for me to get out of bed. I can’t sleep so I’m not getting rest and I feel panicky all the time like I am going to get a pink slip any minute and be completely dependent on my parents. I feel like a looser, and if not for my parents I would be living on the street. At first I tried to ignore all this but I can’t. I keep feeling worse and worse. My siblings who work at a different company than we have just been laid off of their jobs and are at home with my parents searching for work too. I can’t understand how all this is happening at the same time?
I was depress in college for a while (3 years ago) I did yoga and was prescribed mild sleep aids to help back then. But this is deeper. I can’t go two steps without remembering how I no longer have my “own” place to live. How I can’t do the things I want. To make matters worse I can’t afford to see a Dr. Does any one have advise on how to seek help from a Dr. when you can only afford a small amount a month?
