AHh-- First off I would like to apologize because I have actually never posted anything in any subreddit ever so, I'm not sure if I am doing this right

Last night at around 12am I had experienced possibly, the worst type of anything since before I met him. his name is Daniel, Daniel and I were together for 7 months and he was a first for a lot of things and quite possibly everything. And it ended so fast I still want to believe I
am sleeping somewhere

We broke up because (well rather) he told me I was possessive and abusive
And that's the worst part, I myself have been in an abusive relationship beforehand, I found it utterly shocking seeing these words, how could I be abusive? I can understand possessive, I didn't want anybody trying to take away what we had, take him away or even avert his attention from me as well? 

But right now I dont know what to do, I woke up with this sunken feeling like a hole in my stomach, somewhere inside of me.. I can barely type, my hands are shaking and my heart feels as if it would burst, last night as we broke up I told him to call me, he did and I was sobbing, I couldn't breathe, I was begging for him to take me back and right now I'm just waiting for the shame to hit me where I feel so embarrassed as to begging for him to even come back.
<bot>: My first real breakup, I don't know what to do with myself, how to get over it, how to make myself a better person, and how to make this hole in my chest leave.
