How does meth affect you emotionally?

Well personaly i have done Methamphetamine. Not proud of my self i lost my familys trust, along with my family themselfs. But i got so addicted that i just COULDNT STOP. :( i have tried and tried but nothing, i pretty much survived for about 1 year off of dope and mountain dew.:(... It made me feel like i was nothing when i looked in the mirror it made me feel like the ugliest person in the world .. If you are thinking about it... INFO. DONT EVER TRY METH. :( Gina tennisee.
