BAD BREAKUP HELP PLEASE

Hi, i'm 24 and i just had my first breakup, i met him on tinder and we had sex a couple weeks later, he never bought a condom, and i was aware of te fact that he was a duch, in fact i told him that and that i didn't know what was wrong with me that i like him, then we started to see more, i stayed over, we slept holding eachother, it was hard to reah him because of his work but i tryed to see him, he then ask me for exclusiveness and i said yes without asking anything on retunr, he said to me that he will want me forever, that he was all mine and that i was his, every time i spoke about someone else he reminded me that we had exclusiveness, .then i found out he had a daughter ( he posted on instagram ) and a girl comented " she is gorgeous my love" then i found out trough twitter that he was seeing another girl( the girl who comented) for a month and this girl was so inlove she posted everything, pics of him, naked pics of her that he took, apartment photos, etc, i confronted him and the first thng he said was that he didn't had time for this, he as restarting a process with his daughter, he denied everything and said they havent seen in a while, i ask if he liked her and he said " yes, and i don't see a problem" , i asked if he wanted to stay with me and he said yes, he said hat it was ok if i wanted to breakup, he sent me an audio of him just laughing " confused" about the situation with that girl " and said that he wanted to keep things with me if i stayed cool, then i decided to tell him that maybe he needs to work on his own issues and we need to move on, he replied that mybe we should let things like that ( as if he was the one breaking up ) i said have fun, he replied, i'm on it .... that day i had a panic atack and cried all day, couldnt go to class at college or eat , the next day in the morning i texted( and realize he had already deleted my number ) that if i wanted unattached sex i'll call him, he said that sincerely he didn't want anything with me. i kept online stalking him and the girl, had panic atachs, had to call my pssychiatrist and she gave me [edited by Anomalia - medication], my mam had to come to my apartment a take me to hers, i lost 6 punds in a week, haven't gone to classes, just yesterday i started to go again.

i tryed to meditate and have a routine( my routine with him was to check on his social media and if he had written anything) , is hard, i have panic atacks or have anger snaps, my chest aches, i want my life back,

i feel it was my falut for believing, for trying to get him, he satisfyed me sexualy a couple times, he was the first time i felt sexually satisfyed, i wasn't a virgin but i've never went out with someone like this before , but others, in the morning i wanted more and even if i woke him up in a special way he chose to keep sleeping, i felt humilliated as if i was begging, i wante to feel sexually free so he did other stuff i hadn't done before . I remember hat day i felt used as a sex doll, the last time i saw him he introduced me to his best friend and presented me as a friend, i remember he texted a lot before going to bed, maybe it was with her ,I remember once we has a discussion because he was too busy and he said, i DO NOT beg , if you want goodbye. he used to be so different at first , sent me pics every morning, he was obsessed with me and i loves that , but then i was begging to see him, i was inlove and now i feel broken as if i could never meet anyone in a normal way without exposing me on tinder like a piece of meat , i like sex but i don't like to suffer like this, please, please help me ,
