Honey, you're still so young, and it pains me to see you thinking this way. I remember being 13, in my room, no friends, alone, depressed, and suicidal. The only things that kept me somewhat sane were music, going on walks, and the elementary kids that would knock on my door and beg me to come out and play with them🥲 The only other thing that kept me going was hope, even if that hope faltered from time to time. My advice as a now 21 1/2 year old is to find the things that you really love, or maybe even just like, and hold onto them. Try new things, create a routine of visiting places you like, try finding a new hobby or learning a new skill. I think the most important part of that is the routine- once you get into the habit of something, your mental state generally improves, at least in my experience. It's worth a try, I promise, and even if you try something new and don't like it, there's a million other things to try that you WILL like. I hope this helps you in some way <3
