I want to give up on therapy but I can't

I have issues keeping therapists. I miss appointments by accident because of my bad memory. I stopped seeing my 1st one because she was more meant for a child than a teen, my 2nd one was through school and got switched like 3 times. My 3rd one was going decently then I missed some appointment because of weather and I was never able to get ahold of her again. I tried with a 4th one but I, again, forgot about the FIRST appointment and was never able to contact her again. I seriously just want to freaking give up because I swear, it feels like no one cares. I know others may feel differently but it's just so difficult. The worst part is the reason I can't give up looking is because I NEED to make my dog an ESA because she is one to me. She's worked better than therapy and my medication combined but almost no landlords like animals, especially a dog. I found another therapist to email but I'm waiting to get dropped again. I'm so screwed. Edit: formatting and adding a detail.
