I feel so misunderstood by so many people...

I sometimes feel misunderstood by my teachers and my friends and even my family. Why does my life get so complicated that I can't even understand it sometimes? I really can't take this shit anymore! The pressure or the stress of school and life is really annoying me. My teachers are pushing me to do way more things that I can handle. I feel over stressed everyday in school. My friends are constally joking with me and its hurting me weather they think its funny or not it really hurts me. My family doesn't even know half the things I feel or how I see the world. My whole life is changing before me and my life is flashing. I would give anything to be young again or to just be reborn and start a whole new life because right now I feel like my life sucks. I constantally feel depressed and constally worry about death. I have a big fear of growing old and dying and that controls my life sometimes and I often cry my self to sleep thinking of stuff like that. I really don't know who to call my true friends because people I have been calling my true friends at some point really let me down or even hurt me mentally. Out of like all the friends I have right now I can only think of 2 I can call a true friend and I dont even trust those 2 people fully. I feel like I can't trust anybody. I have big trust issues now and its thanks to all the people who have let me down a lot. This is the time I would like to say that only my teddy bears fully understand the real me. I seriously need help but have no one to turn to because I can't trust anybody. I can't trust my teachers or my friends not even my own family. I feel like I'm all alone in the world with no one to talk to about my problems and thats why I'm the way I am because I'm hiding how I really feel about many things. I think about and question so many things that is so complicated there is no answer. Someone prove to me reincarnation is real and I'll stop fearing death.
