Overworked & Stressed

I’ve been working at this job for 6 months now and it has turned from what I thought was a really good job into a stressful nightmare that’s taking a toll on my body. They just keep expecting more from me and getting on to me when I just can’t meet their crazy expectations. At the beginning they were telling me how good I was doing and exceeding expectations ect ect. But now it’s like they just keep piling stuff on me, expecting me to be able to do all of it and I can’t. Like the lead in my dept (not superviser) got onto me for not doing stuff that came in during the last hour of work, even though I had important stuff to do. The way the lead talks to me is very stress inducing. I’ve been having a very tense body all the time and I’m having physical and mental issues due to it. (I can’t swallow properly etc.) I don’t have the energy for anything anymore after work. I know I probably need to look for a new job but I don’t have the energy to do so. I just feel so stuck and overwhelmed. I don’t have money to go to therapy. I’m barely surviving money wise. I just can’t do it anymore and I don’t know what to do.
