Depression has robbed my joy of writing

I've always been a prolific writer, but in December, it was like my creativity hit a brick wall and it hasn't gotten better. I'm med compliant and I've just started therapy again. I may have to try a med change, which scares me. I don't want to wind up back on the psych ward again while I get used to new meds in a safe environment. I don't understand what happened and why it hasn't gotten better. I'm a full-time writer, so it's my livelihood. It took me 8 months to get a book out when I'm used to writing one per every 4-6 weeks. It's greatly affected my finances to the point where I'm barely able to pay the rent and main utilities. My partner is disabled and is on a fixed income, so I'm the main bread winner. I NEED to be able to write so I can make a living, but I just don't know what to do to get my grove back. I can't concentrate and just have no enthusiasm for it. I'd almost rather have a regular J.O.B right now, but I don't have a vehicle, so I can't do that since we live in a rural area. I'm between a rock and a hard place and feeling very anxious. I also feel like a failure because I can't get it together. I don't know what the answer is.

Is there any work you can do remotely since you don't have a car?

And are you doing anything to deal with your depression other than taking meds?
