I feel a complete rut... help!.?

I wish I could die this moment, only thing that stops me nw s my mom. I've a completely irresponsible dad (except that he acts very caring in front of people) and stubborn granma who always blames me and mom inspite of with fact that mom is the only one who cares for grandma & a hell lot of dad's relatives who nvr care except to irritate. It irritates me that mom still provides them help irrespective of wht they have done to us. My parents hve been arguing all the time past 25 yrs. Mom's working hard handling household, work, etc all by her own & recently having health issues too. Ther has been a property issue paralelly these past 25 yrs where relatives r blaming us for illegally acquiring a close relative's propery where we havnt done anything like that, and suprisingly, dad is just bothered abt money and always on relatives' side, always telling lies abt me and mom to relatives. Due to sme personal issue, my marriage is also getting delayd, which is upseting my mom too.
