Stressed out. About to explode. Help?

Okay, so a few months ago myself and my other family members got evicted from our apartment. Because of this we have had to move into my Grandmas house, who is the devil incarnate. Ever since we have lived here she's gone put of her way to frustrate me, such as mumbling rude things about me as I walk by, treating me like **** and trying to antagonize me while I am infront of my mother so I get yelled at. This sounds ridicoulous but it's true...my grandma is a horrible person who gets off at seeing others being tortured. Just recently my Aunt has also moved in with us and she is just as worst when it comes to the namecalling and what not. I try to talk to my mom about it but she just doesn't listen to me. Another huge problem is the fact that I'm the only one that does anything around the house. I do everything my mom, grandma and aunt ask me to do even if I don't want to do it. But when I go off on my grandma or aunt for pissing me off they bring up the fact that I'm supposedly 'Extremely Lazy and never do anything' which is probably the thing that pisses me off the most. I just wish I could peacefully live the rest of my teenage years without all this stress, everything I have tried doesn't work, I've tried being nice to my grandma at all times even if she is trying to antagonize me or insult me, everything I have tried has failed and I just can't take it anymore and I've been starting to consider suicide lately, which I've had issues with in the past. I just need some advice on what I could do to make this situation I have better for myself before I have a breakdown.
