I am very depressed with anxiety on top of it

I need to go talk to someone. I really do. But my anxiety is so bad (something I also need to take care of) that I can’t even call and set up a therapist appointment. I don’t know how to get out of this rut as my anxiety conquers all. I literally panic before making any calls and I put them off for weeks. The only things i can push my anxiety to the side for are my kids. I can make and take them to their appointments just fine but when it comes to myself I just shut down. I know this isn’t normal. I am just stuck.
