Stress relief

Help

So I don't know why I thought everything would be fine now that I had a buddy to rant to and be bffs with and stuff but I did. I'm like 90% sure that my 'buddy' is tired of listening to me rant, I don't rant to him every day and I try to keep them kinda short but I can tell by how he replies that he's getting sick of me.

I've had so many friends leave me and now that I've told him so much a relief on him so much I'm really scared that if he leaves it's just gonna destroy me and I don't know if I can deal with that. I shouldn't rely on one person this much but I can feel myself getting bad again. I can feel myself not talking to my friends as much and I haven't even done my homework and I start school again in 2 days. I'm not eating much but I can't sleep because I'm so fucking anxious and I really wanna text him and just cry but I also don't want to annoy him and I don't know what the fuck to do.

I thought that maybe he's dealing with some shit himself but I've always told him that he can text me and he's ranted to me before and I do my best to be helpful so hopefully he's feeling okay. I want to text one of my other friends because I've ranted to them before too but they don't know the extend of my illnesses and some of the things I say might get them worried because they haven't experienced this sort of thing before so I don't wan to get them worried over it.

I'm really shitty with people so I don't know if I should give him a few days or if I shouldn't text him anymore but I don't know and I'm freaking out. Maybe he thinks I'm annoying and now he hates me. I should stop texting him.
