Ways to cheer up?

I’m going through a rough time right now. This semester in college I did poorly. It’s finals week and I missed one final because I had no one to watch my toddler. I got a c+ in English and I don’t know if I can make up my science final. My history final is Thursday but I can’t even bring myself to study. I’m pregnant and my boyfriend was very supportive until this week. Sunday he told me on Monday he’ll come see me but on Monday he had to fix the car, then he went to urgent care to get a doctors note because he called out of work. I asked him if he can come afterwards but he said he’s tired. I was upset and words were exchanged but okay whatever. I was really upset because I needed his support because of how terrible I have been doing in school because of the pregnancy. In the morning he asked me, am I still mad and still hated him. I explained to him why I was angry. He seemed understanding. He went to work. After work I asked him if he’s coming by me and he says, I rather just talk on the phone. I have seriously had it. I told him to take care and I blocked and deleted his number. A lot of people may think I overreacted, fine. I just can’t be with someone who knows I’m going through a hard time in my pregnancy and in school and just doesn’t give a fuck. I’m hurt but fuck it. It is what it is. What Can I do to cheer myself up and make it through the rest of the semester? I still have a toddler to raise and school to attend so there’s no use in sulking right?
