Here a few was to ask/answer questions to help you move away from being in a "stuck mindset".
Instead of saying " I can't find time for self care" Ask What can I change in my life to find time for myself?
Instead of saying " Therapy will NEVER work for me" Ask Maybe I should try Therapy and see how it goes?
Instead of saying " Nothing will help me feel better" Ask What do I need to feel better?
Instead of saying " I can't do anything right" Ask What are the barriers that causing me to feel this way?
Asking yourself questions maybe a good start for you to find healthy solutions to your problems.
