Hello @Squidly, firstly welcome to the forums, I am so glad you're here.
I am sorry to hear about the darkness you are in at the moment with your depression, I know it all too well myself unfortunately and it is the hardest thing to try drag yourself out of when everything, even the smallest things, feel impossible, you are not alone.
I can tell you a few things that I have done to get me through depressive episodes in the past, things that I found helpful and that got me feeling better over time.
Be gentle and kind to yourself. A big problem with depression is feeling bad about ourselves for being depressed and low energy which just makes us more depressed and becomes a self fulfilling prophecy. Give yourself permission to take it easy, go slow, be lazy, cry, wear PJs all day etc, you're allowed to, you're depressed.
Once you've given yourself that acceptance and permission you can take the next step, imagine you are someone you love, how would you take care of a depressed person? You might run them a bath, prepare them a delicious meal, put their favourite movie on for them or do some cleaning for them? Caring for yourself is hard to begin with so start small and work your way up.
Motivation generally follows reward so reward yourself first. If showering is too hard just wash your face. if cleaning is too hard just wash one cup. If leaving your house is too hard just stand in your yard or gaze out the window. Take small steps.
If you don't mind me asking, do you live with others or by yourself?
