Can I ask if you're seeing any professionals?
If you find one that you like they can be extremely helpful, even if they can only listen and provide some understanding.
Also when I was feeling extremely unmotivated (and really just wanted nothing more than to lie in the dark all day) working actually helped me push through that depressive state.
Obviously this isn't everyone's experience but I found a reason to make yourself presentable and leave the house for at least a portion of the day really helped. It also provides an opportunity to meet new people who may be able to understand you better - or at least bring you further out of that slump.
It's all pretty connect from my experience, working means more money, which means less stress, which will help reduce your depression
Sorry if this didn't really help, it's all kinda basic stuff but sometimes these things are overlooked. Really all I can say is try and stay as positive as you can to the things you can't change
