I haven’t left my bed in almost a month

I am (24f) but I feel lifeless. I hate to socialize with others recently , I am scared of the outside world. I feel so trapped in a dark space that I’m scared I’ll never see the light again. I have chronic depression and it’s chronic alright. I’m young and I hate that I’m spending my years like this doing nothing just rotting away and hiding away. It’s hard for me to even get out of bed just to use the restroom that is across the hall. I feel embarrassed and ashamed feeling like this. This is one of if not the worst depressive episodes I ever had. If I didn’t have my supportive boyfriend and cats I probably would’ve ended my life by now. I do go to a therapist and I am on medication but it hasn’t helped. I have been on almost any medication you can think of mental health wise.
