My mental health issues are getting in the way of my college education

4th attempt at college. I’m failing. Almost done with this quarter. It’s been hard. Only two classes, a job with ever-changing hours, an autoimmune disability, and ptsd. It’s all so challenging. I go to do my homework and I cry because I am so stuck in my own head and I have flashbacks. I’m in therapy. It’s not really working. I’m worried about everything. I’m very worried.
