I hate him so much
Alright, so I have a cousin (16M), I'm (16M) too and to start all of this, last April till June, he lived in my home with my mom because he just came out from the rehab center and he had to attend some court meetings here in my city. So what I am angry about all the time is the moments where he keeps on coming in my head, he always tricks me, for example, he asked me to have my wifi's password because my mom said so but when I asked my mom, she didn't say anything, I got tricked. And another moment is when he tried to steal my laptop at like around 11 PM, luckily I was still awake and then my phone alerted that someone was trying to hack into my google account, so I went to his room (f\*\*k him), he has my laptop and I asked like, "hey! give me my laptop back!" I got it and so I went to my room, and at that moment I had a mental breakdown, I was so angry and I think that was my first time that I had a mental breakdown related to him, and so even when he finally left my house to live with his family in the province, these moments are ALWAYS REPLAYING IN MIND. It's too much that I always have a mental breakdown, whatever I do, I think of him, I always think of revenge and stuff, punching the air and so on. And that is why I need help, please just make him get rid of him from my mind! My mom keeps telling me, simple, just stop thinking about him, well, that doesn't work, those moments are just too much that I keep thinking about it and having mental breakdowns about it, anger issues. So please, does anyone have a tip to help me? I cannot control my anger or my emotions...
