Please help, I don’t know what to do.

Btw, we are both turning 15 in November

I don’t know what subreddit to post this in or what to say here I just really want help. Basically, I’ve been with someone for a few moths now and recently she sent this message that I will now copy paste:

“I think need to break up with you. I just don’t feel romantically attracted to you anymore, plus with everything going on in my life at the moment, I am not in the right headspace for a relationship nor can I put energy without being overwhelmed with everything. I still care about you, alot, but as a friend. I’d still like to be friends. Don’t have to respond immediately, take your time to process it.”

I said this in response:

“Alright that’s fine, but is it ok if we are still together but just a bit more distant? It’s ok if not. Also you don’t need to put too much energy into our relationship at all, you can just be there. Again, you don’t have to, I’d just appreciate that. I’m fine with being friends if that’s what you need tho”

I sent her a few more things but she is offline now, idk what to do, think, or say. This is only my second relationship and I understand that everything will be ok and that is how I am dealing with this, but if I’m being honest I am on the verge of crying right now.

Also I have many things that might affect my response, I don’t know exactly what they each do tho so imma just list them. I’ve been diagnosed with these however I don’t know many details because I haven’t asked my parents anything about these.

ADHD, OCD, mild autism, anxiety, and probably other stuff I don’t know about or can’t think of right now.

Again, I know that this won’t last forever, and I know she still cares about me, I just don’t entirely know what to say. If you want to know the other messages I sent, please tell me. Sorry if this made no sense, I feel really shaky and my heart is racing. I had to stop typing this a lot of times to fix typos from typing so fast and even then I still probably missed a few. Thank you for reading and please help me, internet strangers
