Struggling with asd and mental health

I am struggling so much with my asd and my mental health. Together they are unbearable. One plays against the other and I'm caught in the middle of the storm. That's what it feels like just being constantly thrown around in this blizzard of darkness. 

I've been struggling for 6 long tiring years but kept going because I thought it would get better. But in reality it's got worse. Things are horrible in my life now. My mum is sick now. My dad has his own mental problems and I'm feeling like I am at the end. I can't do this much longer. My life is just an endless dark place where I keep getting kicked down over and over. No one should have to live life like that should they. 

I'm constantly masking, putting on a brave face being the strong Eve that everyone in my life knows and loves but it's breaking me. I am crushed. Hurting. I cry all the time, my emotions all over the place. I get bursts of rage. I just freeze and can't move just lay there. And I burn out and then sleep for hours and hours. No energy.

A part of me just wants this to end now. I can't go on like this. I'm not eating. I'm hardly drinking enough. I can't process what's happening in my life. I can't figure out how to make it stop hurting. My parents are always there for me, always know what to do. Now it's my turn to be there for them and I'm such a loser I can't do it.
