Not to echo the sentiments shared above but, other than the fear of the mess I'll leave behind and my inability to plan for it, I stay alive by trying to take it day-to-day. Every day until I either get better or decide to end it, I just have to make it through. I just have to keep going until I can get in bed again. That's what I tell myself.
I'm fortunate enough to work even if I dislike certain parts of my job right now and the routine of doing that every day, while it makes me miserable, gives me something to do. And I can't be alone with my thoughts, either. I've had headphones in my ear 24/7 since I was like eleven, lol.
Then there are things I can look forward to in the future. Going to my favorite restaurant every month. Getting to decorate my Animal Crossing island or Stardew Valley farm and seeing the progress in two months. Groups and artists that I really like will continue to make music and release it soon. New seasons of shows that I enjoy will eventually come out. I write with other people and every day, I wake up excited to see where their reply will take our story. My friend has a baby and she surprises me with pictures every now and again, sometimes a voicenote or video where a toddler is excitedly telling me "hi". Sometimes my parents call and I can hear the dog I had to leave at home barking happily at the sound of my voice in the background. These are the tiny and probably pathetic things that keep me going on a daily basis.
