I’m a mess

I think I’m in love for the first time. He definitely likes me too but we don’t feel comfortable dating. And I mean it’s been great until yesterday. We were talking with another one of our friends but when they left, he immediately broke down and started crying, which he only felt comfortable doing with me which is why he waited till our friend left. He was just stressed, nothing too serious, but it really shook me up. I worried about him all day and had 3 panic attacks that day because I was so stressed. I’ve never cared so deeply about someone and yesterday made me realize that. Caring about someone so much more than myself kind of scares me and it’s really unfamiliar, and I was hoping to spend some time with him to figure it out a bit, but he just left for vacation (he just told me he was leaving today) and he doesn’t have a phone at the moment. Which I hate because we talk or hang out literally every day and this is probably the worst time for me to not be able to do that. I’m just so stressed, becoming aware of feelings I have for someone, feelings I’m having for the first time, and not being able to address them, all in the span of two days. And I have no one to talk to about it except to post it here, as my friends don’t care and my family is too busy to deal with my stupid teenage emotional baggage. I just needed to unload. This is just really hard for me, especially because my mental health has been getting worse. It just feels like nothing matters and there’s nothing to look forward to
