I’m just going to explain what I’m feeling and I hope someone could have maybe similar experiences or just some good advise. I hadn’t seen my girlfriend in about a month because of the lockdown in my area. A few days ago we met up in a park and it was really good I missed her. Towards the end of the day I look in to her face and felt some sort of realisation. I can’t explain it very well but it was almost like I realised that I existed I guess it was such a strong feeling. I know that’s extremely vague but I don’t know how else to put it. It’s happening before and it was when I was with her but I don’t know why. After that I forgot about it really but it started bugging me today because I feel it might be something to do with her or our relationship (and I really don’t what there to be some Unknown issues on my side) purely based on the fact it’s only happened when I’m with her. This really disturbs me. While I’m writing this I’m shaking and have a lot of adrenaline I don’t know why. I’m thinking this could be due to that fact that I mostly talk to her over FaceTime because as I said before we are in a lockdown. But I don’t know. I’m saying that a lot. Sometimes I also feel like everything I do is like I’m on auto pilot but that feeling is definitely way less intense then what I was talking about before and is more of a thought than a feeling and it also doesn’t make much sense in my mind. But again I don’t know why. Can anyone help me with this? 
I don’t know if this will help but for context I guess I’m 17
