small tips for Enjoying Being Alive from someone who went from wanting to die to genuinely loving life. these won't fix your life but they'll make it a lot easier to want to live day by day. I promise.
tell yourself things you do not believe. it feels stupid at first but I've done this for years and now I believe it when I say "I'm good at this" or "I love myself" or "I deserve good shit!"
make a note of every mundane good thing that happens to you. mental or literal notes! could be as little as "the sky is a nice shade of grey, it's calming" or "I ate a piece of fruit today, I'm looking after myself" or "I talked to a friend". again, feels stupid at first, but I genuinely believe this is part of why I have so many "good days". trick your brain into storing things in your long-term memory that you wouldn't otherwise remember.
diet deficiencies can make you properly miserable. your physical health impacts your mental health more than you'd think. get some vitamins, some omega-3s and so on. whether from food or supplements. they can make quite a difference! your brain is responsible for a LOT of the way you feel, and giving it the fatty acids it needs to function at its best can go a long way.
