OP, we are not trying to be judgemental. We, all of us, understand your pain and what you're going through; we've all been through it to various degrees.
What we're doing is pleading with you, we're begging you, to reconsider. We all know this is your decision, and we will respect whatever decision you make. None of us are calling CPS, no one is calling the cops on you, and no one is mentioning the suicide hotline. We all recognize you're in control and we are not trying to take that agency away from you.
But many of us know the scars and pain that will follow your children for the rest of their lives. We're begging you to not do to your kids what was done to us.
I understand being depressed. I understand wanting a way out. I understand being in constant agony every second of every day. And I am truly sorry that life has dealt you this shitty hand; I would do anything to take your pain away. But your mind is telling you that your kids will be better off without you, and I don't agree with that. Your. Children. Need. You. Please don't assume this will improve their lives.
It sucks that mothers don't get the support they need. It's not fair that so much is expected of you after you've already given so much. It's bullshit that you can't ignore everything and just care for yourself; we understand. And if you want to scream at the void and vent and yell everyone how unhappy you are, we will attentively listen and give our condolences. But regardless of all the pro-life hate I'll get, I really, honestly, and truly hope you can find a way to be happy AND be in your children's lives.
