Help me please

I’ve struggled with depression for a long time. Sometimes I feel better but then it just gets bad again. I was on medication but then I stopped taking it and the doctor just prescribed it again. I have a car but my fiancé uses it to go to work and back. I’m a SAHM until classes resume in the fall so I never leave the house. I asked my fiancé to pick us the prescription for me yesterday but my insurance wasn’t on file and he didn’t have my card so he couldn’t. I’m going to go today when he gets home from work. But all day I’ve felt on the verge of crying. Nothing has happened that’s particularly different. Yesterday I was irritable and getting mad easy and today I just want to cry and tomorrow who knows. I’m so tired of fighting with my moods and emotions. I just wish I could control them. 😭 idk what to do and I have no one to talk to. I’ve been to a psychologist but the only one in town doesn’t take my insurance and the pay just became too much. I can’t talk to my fiancé bc I don’t know how to explain how I feel
