I’m not looking to get diagnosed on here or anything, all I want is to get some advice on if I should go see a professional. 

So I’m 16 years old and I can remember this first being a problem since I was around 10. I get jealous really easily I think. I’ve gone to the emergency room on multiple occasions because of how my boyfriends actions effected me. He wanted to play video games with his friends instead of with me and it caused me to spiral and harm myself really badly. My mom thinks I have depression and the reason I cut myself was because of my grades but in reality, it was because he wanted to do something with his friends. This happened again a few hours ago where I cut myself because he made plans with his friends this Friday instead of wanting to spend time with me. It makes me want to kill myself and I feel like the world is ending when he wants to do something with someone else. I have a mental breakdown whenever I find out he’s hanging out with other people. Like crying to a point where I feel nauseous and I feel like I can barely breathe and this happens like 4-5 time a weeks. I hate him so much for the way he makes me feel but I don’t think I could live without him. I started playing the same games he likes, listening to the same music, and just liking the same foods because in my mind, he won’t like me unless everything is similar. I have sex with him even though I hate it because he likes it and I feel like I have no personal boundaries when it come to him. I’ll just do anything he want to so he won’t leave me because my biggest fear is that he’ll leave me. Whenever I’m with him I feel so happy and he does so many nice things for me but its all forgotten in my mind when he doesn’t respond to me within 5 minutes or even talks to another girl. I don’t know why I’m like this I just want a healthy relationship without wanting to kill myself because he doesn’t want to spend every second of his time talking to me.
