I am 6ft 2inch tall and moving to a more dangerous area so i want to learn how to self defence, guns are not allowed here and carrying a knife with me everytime is risky since i dont know how to use one, there are no martial arts school or classes in the area, so i am wondering how do i go about learning self defence and practising it, i have tried youtube but there are so many channels and i dont know if they are legit so i am open to recomendations about where to get this knowladge from and how to practise at home.

I hate my life, its shit, i had exams in a month and i wasted 3 weeks wasting time on my phone doing god know what, i hate this shit, why am i like this? I dont want to study, i hate exams, i dont want to live this shit show of a life, i hate my future, i hate what i am going to become i hate everything, these times are so shit, there is nothing that brings me joy, everthing feels like a drag, i dont want to do anything, i want to bash my head into a wall, i hate this, i hate that i am going to become a doctor, i hate my parents, i hate my family, why would they think i can ever become a doctor? I dont have social skill, i dont have any knowledge, i dont want any knowledge, i dont want the stupid fame that comes with this shitty noble job ill have to do, i cant even study, i dont even know where to start, why are there so many exams, i hate everything, why is the world like this, why am i like this, i hate myself, i dont want to study, i feel like a kid throwing a tantrum because exams are coming and i havent studied i hate that, i hate the people arround me, i hate the teachers, i hate this shitty education system, i hate my life, i hate that on top of all this shit somehow i am suppose to take care of my mental and physical health, i hate this shit, i hate going to the gym when there are other people there, i hate eating food with other people, why cant i just live alone forever without talking to anyone for ever and ever, i hate being with people, i hate people, they are so stupid, i am so stupid, i hate i am like the people, i hate my studpid self, i hate i am a glutton, i hate i spend my time masturbating to awfull shit on the internate, i hate i am a porn addict, i hate i am a phone addict, i hate i am addicted to anything that gives me quick plesure and fucks up my brain chemistry or whatever, i hate i dont have time to do the things enjoy and even when i do i feel guilty because i am suppose to be a doctor and save lives of the people in the future, i really dont want to take such a big responsibility, i hate i can go agaisnt my parents and that i have to do waht they tell me to do, i hate what i am going to become i wont be living a life what i want but one they want me to live, i hate that my life isnt even in my own hands, i hate exams they turn up the tention so much allready there is so much shit to worry about how the fuck am i suppose to study on top of that, i hate that even after saying all this shit i am still wasting my timeon phone even tho i have got important shit to do and still i am not doing it, i hate everything, i just want to cry, i want to cry, tears wont come out, i am an emotionless peice of shit, why am i like this, why am i so mean to myself, why cant i treat myself more nicely, everyone is mean to me, i feel even the people who are nice to me secretly hate me, i hate i have trust issues and cant trust anyone, i hate this feeling of constantly being uneasy, i hate how i have no close friends or family who i can share this with or talk to, i dont trust anyone i have trust issues, whats even the point of venting here ots just a waste of time an excuse to avoid studying and actually focus on the things that matter but if i dont vent i will just waste my time on phone and waste these moments fail my exams i am allready in student debt i hate how i havent bathed in weeks or brushed my teeth in months i hate everyhting about myself.
