omg i seriously am so stressed

i am so confused on what to do....i have to listen to a suicidal dad all the time... :( its not fun at all...plus i have to listen everyone yell at me about every little thing. i have no concentration at all....i can never just be happy without someone or something ruining it... i have to put a fake happy face on everyday and act like im happy so no one will ask me "What's wrong gurl" i hate when people ask me whats wrong because it just makes me more upset because i dont want people knowing that im a depressed person a lot. my dad is having troubles with a lot of things.... my friends yell at me everyday....my teachers try to get me to be optimistic and try to get me to do hard and success in things but sometimes from everything (thats horrible in my life which is everyday something destorys my confidents and things) thats been happening in my life so i just think about giving up. lately ive been wanting to drop out and run away but im making myself stay here and try to succeed in everything possible.... its just so hard with so many things that are happening in my life...... its pathedic but oh well i guess i just have to live with all these rough times and try my best to be happy!!!! but idk if it will work......... i can hardly never sleep at all... i barely do my homework because i just want to give up on things but im gonna try for the best for my friends, teachers, boyfriend, and family.......but most of all i want to show kiah that people in the price family can be successful.....
