I just broke up with my girlfriend

I just broke up with my girlfriend and I'm feeling so lost. We had been together for close to 11 months and have known each other for around a year. I think we both knew it'd end up like this for awhile now even if we didn't want to admit it. A lot of our issues are hard to word, but button line is a of her behaviors really hurt me and made me feel unloved and disrespected, which we had talked about many times but nothing really changed in the end. I'm by no means completely innocent in all this, I shouldn't been more open with her about how her behaviors affected me and put my foot down from the very beginning, and I know I wasn't the greatest all the time either. We both struggle really badly with mental health which resulted in an unhealthy codependent-ish attachment and had horrible communication which resulted in a lot of hurt. We we're also long distance, we live around an hour away for each other, and we hardly got to see each other. Neither of us we're ready for a relationship, especially not a serious one. This was my first serious relationship so it's hitting me pretty hard. She's really such a sweet wonderful person and it really hurts that it came down to this, I really didn't want it to. I don't think the fact that we've broken up has really set in yet, but when it does I know I'm gonna be a wreck. I'm wondering weather I made the right choice even though I know that I did, others around me are telling me that I did as well. I know that I needed to in order to grow. It's really gonna suck getting used to not talking with her daily, I'm not sure how I'm gonna cope with that. She struggles really badly mentally and I'm so worried for her safety right now, but I know that it's outta my control and that I need to focus on me now. The first bit of the conversation was very messy as both of our emotions came full force and we we're texting so the tone was hard to tell, but we called afterwards and ended on a good note thankfully. We're gonna try to be friends and give it a few days then check, distance ourselves, then check back in, distance ourselves, etc, and just see how things go. I just turned 18, so I have a lot of new big changes coming my way. I'm moving out of a toxic environment which means I'm leaving my siblings who are like my kids in a way, my dad's trying to stop me from moving outta said environment, I've finally found another job, I'm going to therapy, and I broke up with her. I'm just very frantic right now, this is a lot at once, and I'm not to sure where to go from here or what the next step is. I know that I'll find it, but wow is this confusing.
