Stop... please...

Could those who only want to use me, just please not bother? I can not take anymore abuse. I am a human being. I have real feelings. I treat others with respect because that's how I expect to be treated. I give my all to everything I do. I hate not getting even a fraction of that in return. I'm trying to stay positive, but it's growing increasingly hard given all I've had to endure. I'm just not sure where I'm going to find the strength to continue if much more goes wrong. It's more than anyone should have to handle. I feel broken.
