Struggling mentally

I am really struggling. I have an almost 2 year old and a 2 week old. My 2 year old is in his terrible 2 stage where he doesn’t listen and throws ridiculous tantrums. He is a mommies boy and is up my butt 24/7. My 2 week old won’t let me put him down for longer than 5 minutes. I have a clogged milk duct because I can’t pump on a regular basis because I’m either feeding one of my kids, holding one of them, trying to eat my own food, putting my oldest down for a nap which completely back fires because he screams and wakes up my 2 week old which then starts a carousel of bullshit. On top of the little to no sleep I get at night.

I don’t feel like hurting myself or my children, but the depression is really starting to mentally kick in. I am completely overwhelmed
