can there be some1 too angry???

so thge past three days have been really shitty. in short:my sis didnt invite me to a party tht almost all her friends whom are my friends were going to.one of my best friends is acting like a bitch.the girl i love is still taking me for granite.my parents drug habit is getting worse.and ive been alone at lunch for like a week now cuz all my besties have BFs T.T most of my anger right now is from my sister. ive felt this pent up rage that is growing too rapidly for me to handle. i cant sleep at night cuz i literally shake from anger. im tearing up at random moments! and my stomache hurts so bad when i see my sister. i dont fucking know what to do anymore!! i just feel like shit all the time, im tired 24/7, and im going downhill in school. i feel like nothing can save me n nothing wants 2. my chem is all i have these days but i still get lonely.
