I know how you feel. I often feel like there are two sides of me dueling in my head. And I understand how annoying it is to hear those phrases, but frankly most people just don't know how to deal with other people's mental illnesses. I know it's hard, but try not to let it get to you. Surround yourself with things that you like, whether that be animals, music, art, whatever. If someone is hurting you, then don't waste your time on them. Sometimes people try to help but they just can't, and it's not their fault. It's not yours either. Life really really sucks, but it's not all bad. Most of the time it's hard for me to see that, and I'm sure it is for you too. Just please don't give up on yourself just yet.
