Will I be able to get over this

I hope some people reply to this and give me some good advice.

I’m 17. I’ve just broken up with a girl that I’ve known since I was about 5 years old. Went to the same school for over 10 years and have been dating for around 4 years.

Now I know most of you are gonna say things like “you’re too young to have a proper relationship” and try to make it out like it isn’t as serious as adult relationships- but this girl was and is everything to me. We spoke every single day, and were together all the time. She was literally the only person I’ve ever loved and felt like I could speak to. I have no family that I can speak to, and none of my friends either. She is literally the only person I have.

We broke up about 2 months ago and she’s still all I think about every single day. I still have hope that she still likes me and will come back, but deep down I know thats not gonna actually happen. Right now it actually feels like I’ll never get over this and find anyone else.

Idk how I can really express how strong our bond was, but please believe me that it was incredibly strong, even though we’re still young, I knew that this was the girl I wanted to spend the rest of my life with. We talked about spending our lives together and starting a family and stuff, and now it’s all gone. She doesn’t seem to be affected by not speaking to me at all, whereas I am. To her it’s like I don’t exist and never have, but to me it’s like she’s all that exists and ever has- I literally can’t think about anything else but her. Will this be over? Has anyone seeing this experienced the same thing?
