Depression is taking over me

I’m 22 and I’m 12 weeks and 4 days. I’m in a very stressful situation that I don’t know what to do anymore. I feel hopeless. I try so hard to be with my boyfriend(who’s also my unborn baby’s father) but we fight a lot. I love him more than anything and I can’t breathe without him. We had another fight this morning and he threw my stuff outside when I had to be back at my parents house at a certain time. He blows up but then he’s all sweet and everything goes fine and I feel happy and then it’s all over within minutes. Idk what to do. I want it to work with him I need it to work. I’m scared and alone and my depression has gotten so bad since I found out I am pregnant(found out on Christmas morning). I want everything to end.. I want my demons to leave me alone. They are winning this fight and I’m ready to give up
