2020 trainwreck

As a whole, 2020 has been very hard for me. I just started college this August, which in itself is amazing, but I am struggling outside of that. I was working two jobs until March when the virus caused everything to shut down, so I decided to take the first opportunity that came my way. On April 1st, I took a position at a local company. The company I agreed to work for said they HAD to put me on second shift, 3pm-1am, but that they would bend over backwards to accommodate me once I started college and I would go straight to 1st shift. I struggled with my mental health so much during that time on 2nd shift, I never saw anyone outside of those walls. Not my family, not my boyfriend, no one. I was just holding on to the thought that it would be over soon, I would get to go back to day shift. Two weeks before I was supposed to start college, I inquired as to what day would be my first day back on a normal schedule. The company claimed that they never made such promises, that they had no idea what I was talking about. I was absolutely shocked. I knew I wasn't in a good place mentally and I knew I couldn't continue the life I was living, I only get one chance and I don't want to spend this life alone when I don't have to. So I continued to push the subject, talking to as many higher-ups that I could get to. I was running on 3 hours of sleep a day, trying to manage my schoolwork, and I was still struggling mentally. Finally, the company came to a resolution. I clearly couldn't work 2nd shift, so they cut my hours. I went from working 45 hours a week, to 18 hours a week. I am a college student entirely on my own, I pay for my phone, my car, my insurance, my apartment, I am paying for college out of pocket. This was no longer livable. So, I saved as much money as I could through September, and my last day was September 21st. I am now unemployed and running out of money, I don't know how I am going to pay for anything that I have. I did not anticipate a job search being this hard, I have been turned down by so many companies I can no longer count. If anyone has any advice, please let me know
