Help me identify this please

It's not strictly a relationship question but it happens in relationship setting. So here it is:

I think I'm a little low on emotions. This isn't for sure. But I'm a 21 year old male with an attractive-enough face. I have never had sex and never had a real and lasting relation ship. These are for statistics.

I'm using Concerta since January, so my dopamine levels might be lower than normal which can contribute the emotional problems and seeking-sex. Now It's been 3 months and can't say it did helped me that much for attention but attentions and libido is, i think, a different story.

Will try to cut it short now. I was talking to this girl from Facebook who lives in the city I live in but studies in other. Frequently visits the one I live in though. She was friended for like a month but we've never had a real conversation then one night, I think it was like last Saturday -so it's been one week, we've talked around 8 hours with the tempo and our attention to the conversation was slowly shifting up to the very engaging levels.

I have told this to her too: She was really the one in like five years that I really talked to have in my life. She's in deppresion, just broke up with his practically first lover-like. After talking until this Friday, last night, everything was fine. Then I told her I was about to break my neck, belly whatever in order not to 'cheat' on her in bus. But then she said that's sad because she's doing it everday and she's sorry for that. By the way it's, I think, really not about she's doing I dont know what with person(s) although she did say she wasn't contact in with any male because of the break-up period. I shouldn't be feeling anything even if it is so since It had not been a week since we have first chatted and we didn't meet in real life.

But at the exact moment I read what she wrote to me I have started to feel weird. Like... Got little disoriented, dislocated. Like I was far within me. Then I don't know it was emotions but I got hot. My brain felt hot especially the very back and end side of it. That 'flame' stretched through my back of head to my spinal chords. I was caught up by it. And with this state of emotion -if it's ane motional state, memories came. I remembered that last time i felt like that. Like something unjust happened to me, when I really didn't deserved that. And I was in a situation where only words of apologies can be said which meant nothing. Like I was this person doing nothing and the one I'm related with was doing actions that thrash over what i do and so i was left behind.

She said she was sorry and we should make it up. Then she said she was just joking then in 30 minutes I got stabilized a bit. Then continuing the conversation she meant that she 'cheating' on me was real. I think... I was really in no position to properly act, understand or communicate. Then that flame came back the same way. I understood that I shouldn't be continuing this having a 'constant' in my life road and said farewell then deleted, blocked her.

I'm like that right now now that I'm remembering yesterday. And yesterday I remembered the last time I felt like that. Since then it easied up a bit first and then came again, then I once again remembered else, which no matter how i try I end up this state. Then i decided to remove her and the idea of having a romantic partner.

My problem is right now is not myself having a romantic a partner. I'm curios with this 'blockage' if I'm pushing away some personality, emotion off of me? I don't think that's random this happened in while using Concerta, but it might be so. I don't think my that part, that fury, or bulk of emotions and it's memories is controllable to be honest. I really feel like that state is a flame and I shouldn't be getting close to it because it burns. I might continue to write things but for introduction these will do enough i believe. I might share further info if needed for you to evaluate.
