How do I handle stress? (Free choice)

Honestly isolating myself from everyone and everything gets me to help me breath from so much stress. I don’t like to be around people when I’m annoyed or stressed. I like to hear music and just listen to the lyrics to help me get through rough days. When I’m stressed I feel like I’m trapped, and I can’t get out of that situation, that gives me headaches. When I’m around people and they’d be talking you’d see me quiet just thinking over and over of the stress causing me. When I’m doing that it feels like I’m doubling the situation. I want to be left alone, however knowing I have a shoulder to cry on will help me reduce my stress. Most of the time around people and that’s why the only person that understands me when I’m quiet is me best friend she knows I’m actually about to the point where I’m going to explode and either yell or cry to someone if I’m being spoken to. I have this tendency because ever since I was little I was always the one who isolated her emotions and rather bottle them up until I can’t take it anymore. I like being alone when I’m stressed because I’d be able to cry and hear music to get that rage off my chest. I can’t stand people watching me suffer and seeing me weak. And I don’t feel like anyone would understand me, but me. That’s why i feel as if only i can get rid of my stress by being alone and doing things alone. Also, when im stressed, that stress turns into rage, then that rage always turns into sorrow and sadness. And like I said I don’t like giving people the privilege of seeing that side of me. Who else but you can understand you though right?
