Mom passing and intrusive thoughts

Today my mom broke down crying because of how much stress she feels having to take care of me, she said I can’t do anything in terms of being able to take care of myself and she’s right I can’t, she breaks down constantly because of me, I don’t know what to do, it’s been like this for years, part of me feels like the only way to save her is to kill myself, I don’t want to die, but it feels like the only way to set her free, I don’t think anyone but her would miss me anyways, I feel utterly hopeless. I’m not going to do anything to myself the voices are just SCREAMING that I need to. I can’t work, I can’t go to school, I’m trying desperately to get therapy, I don’t know what else to do, I wish I was a child again and I felt like I had a chance to be okay. I love my mom so much and she loves me and I’m killing her, I’m actually killing her, with how fuckinh worthless and pathetic I am, it’s too much, I miss being a kid.

TW I am so utterly broken. I feel like my heart is shattered to pieces, within the span of a month I have lost someone that was like a second mother to me and someone who just passed away that was my closest connection to my great grandmother. I am having very taboo thoughts (as well as physical responses) surrounding death because of OCD, while also carrying such a massive weight of grief. Idk if taboo thoughts with death are even normal, while it is overwhelming me, I’m also so numb to grief at this point. Can anyone please give some kind of advice on how I may improve my mental health without overwhelming my family during their time of grief? I’m so tired of being strong, but right now I absolutely have to be. Any advice would be greatly appreciated.

So I had a panic attack a while ago to “kill mom” and I forgot about the thought until a few days later. When it came back I was mentally drained and it lasted for 2 months or more. It eventually went away but it is back. I get other intrusive thoughts but they go away after a hour or so. Why am I stressing over “kill mom” so much. I just get irritated that it won’t go away. I’m beginning to think it’s a different mental illness maybe just anxiety? I’m not sure to be honest. It just appears and sits there and I feel like I’m doomed and a pyscho and worry that I’ll never forget the thought.
