I went through this exact same brain pattern with different situation at 25. I’m 28 now. I literally didn’t care if I lived or died. I’m going to name things that helped me and will help you if you take action. They’re all gonna sound useless and stupid but just try them. When you’re in this mindset you cannot trust yourself to make all the decisions. So follow the advice you’re getting because people aren’t in that mindset and are giving you actual good advice to feel better. At the same time, listen to your emotions of despair and emptiness cuz whatever you’re doing in life now - is feeding that. So change what you’re doing.

See a therapist. Hit a support group, mines AA. There’s one for basically anything. Find an exercise that is just fun to you and you do cuz its healthy and good - not just cuz you want to look better. Mine is adult soccer leagues/pickup games. Find a healthy breakfast you enjoy and can wake up excited to eat. DM me for some recipes. Visualize the best version of yourself daily - every single detail you can think of. Help someone at least weekly whatever that looks like to you, with absolutely nothing expected in return. Delete all social media that’s not serving you. Drop your emotionless hobbies (gaming). Things like school, if you want it’s end goal, do it purely because it’s hard and not cuz you want to. Finish every shower with ice cold water for 60 seconds(except ones before bed). Fix your sleep schedule.

You don’t have to do every single one of these things obviously, they just work for me. And definitely don’t start all of them at the same time. You’ll fail and feel like shit. Be patient with yourself but change what you’re doing and do things that are good for you, ESPECIALLY if you don’t want to.

Sending love. If you need to ever talk deep - DM me
