Hey, just because people "have it harder than you" doesn't make you any less valid or worthy of help.
I remember being in a similar spot to what you're feeling now, and yeah, it sucks. You just feel... empty. Emotion kind of just recedes, and you feel like you're some sort of ghost. It's almost like you shut down your more intense thought processes because you know it'll lead to more self-loathing.
I'm not exactly sure what to tell you. I know people blab about self-compassion all the time, but try that. It worked pretty well for me, at the very least.
And, keep in touch with friends. My friends were basically my lifeline, and acted as one of my best coping mechanisms.
And, remember that there are people out there who care about you. And if all of them care about you, then you can reason that there's obviously a reason to care about yourself too.
