All I can do is love you to pieces

I don't like being sad. I don't like having wicked headaches. I don't like hurting. I don't like bio. I don't like failing bio. I don't like thinking all these stupid thoughts.
Is having things get better so much to ask for? I can feel myself falling apart with every bit of stress that comes into my life. It doesn't even matter what it is. Anything that would cause me the slightest bit of stress makes me slowly fall apart. But it's thickening, and the speed that I'm falling at is quickening, and I'm getting sucked back into a world I ran away from years ago.
I don't know what to do anymore.
