Overworked at my Job and I don't know what to do!?

Currently I work at a kennel where I work in the morning and evening. I've worked here for about 1 1/2 years and just recently I wanted to start school back up. I was the manager but when I asked for another day off I said I could step down if needed to. I was asked to step down and put back on the pay role rather than salary of 700. Recently I been getting ready for school and my Pawpaw (grandfather) passed away. Everything has been very stressful but I still try to do my best at work. Just a week ago my boss asked me to come in early despite the fact I was going to get my car fixed. None the less I went in early and canceled my car's appointment only to find out that he wanted to tell me I was getting put on a 30 day probation. I thought I was doing good and was working on getting everything kept up for the front desk. He was telling me all of these things that I didn't do. I tried to confront him and tell him the other stuff I did but in his eyes, it wasn't good enough. This wasn't what set me off, he accused me of lying and told me dead in the face I was. When I told him I wasn't he just dropped the topic and kept telling me my work wasn't good enough. I honestly don't know what to do. I started looked for a few new jobs just in case but then this week happened. I normally have Sunday's and Monday's off for school and family. Monday is my biggest day I need. When I told my manager (the lady who took my place) that I need sunday and monday of she didn't know if she was going to be able to give it to me because it's only me and her and our boss hasn't found a new co-worker for us. I'm coming home tired and nearly falling asleep as soon as my butt hit's the sofa or my bed. I also feel like every day I could go into work and be fired on the spot for not doing one thing. PLEASE HELP!
