I did something dumb

I met this friend in March, and I think the friendship has been decent, at least from my perspective, I don't know how things are from his

I have ADHD, it was untreated for most of my life, but I started medication (atomoxetine) at beginning of July. This friend has autism too. I just figured these things are worth mentioning

He's been pretty busy lately, with work stuff, and I guess distant because of it, and it really made me nervous. I'd asked him a few times in the last two months if he wanted to "hangout sometime this week" and he said yes, every time, but he never got back to me. It just made me anxious, feel like maybe he didn't actually wanna hang out

But now more context specifically for the dumb thing I did. 5 days ago, I sent him a few messages asking to talk, about how maybe we should try and figure out a better way to organize hangouts, whenever he has the time to talk, and that there was no pressure, and then I left it there, silent for a few days, cause I didn't wanna overwhelm him or anything. A day or two later, I sent him something funny, with a message saying "I was gonna be silent for a bit, but this was funny, so I wanted you to see it" and he saw it, I messaged a few minutes after he saw it, saying I was just being silent cause I didn't wanna overwhelm him

Now for the dumb thing. Last night, I was ruminating a lot. I've been really nervous, because I guess I was doubting the friendship, I mean, it's been 5 months, I hope it's acceptable to feel nervous about that. I sent him anxious messages multiple times over the span of a few hours, sending and unsending cause I just kept ruminating on it and I was just really anxious. Finally, I stopped, with a message apologizing for sending a bunch of messages and unsending them, and telling him I had just been feeling outta wack, cause of rejection sensitive dysphoria, and that I hope he can understand

I worry I've messed things up, but around when we first started talking, I felt really nervous, and asked if he'd tell me if I was too much, and he said "I will" and to not worry because he's "like a dog, it's hard to push me away". I don't know, it's been 12 hours since is ent the apology, I haven't heard back from him, I just hope I haven't messed it all up
