Plz don’t judge ..

Could use some advice? Mom to mom,

I’m at my breaking point, I don’t know what to do, I’m so overwhelmed and frustrated, I have so much anger built up inside that I stuff it all in and keep going and I can’t do it anymore. My babies father, (my 2 year old and 7 month old) doesn’t help at all. He refuses to buy anything the girls need, refuses to help, refuses to be apart of their life. Meanwhile, I bust my ass. I literally am working 2 jobs, I get no days off. Beginning of the week I’m working for the apartments we stay in just so we could get some $ off the rent. Rest of the week I’m at my other job. I get daycare m-f, so weekends I’m with the girls. That means going grocery shopping, barley getting to clean, or shower. I feel like I’m failing as a mother even though I’m doing everything in my WILL right now to make sure these babies are okay, feed, bathe, ETC. why do I feel like shit! Why do I feel like I’m the worst mother ever? I would never hurt , harm, curse, or take my anger out on my babies ever. But I just don’t get it! I cry because I cannot give my 2 year old the attention she wants / needs meanwhile it’s the same equality for my 7 month old, she never wants to be put down! I even tried the method of letting her cry it out.... I ended up punching the counter and hurting myself 😞 I just need to hear that I’m not going through this alone... or something? Some motivation? Because I swear, my girls are the only thing stopping me from wanting to leave this earth.
