Bad dad

I think my husband is a bad dad sometimes. He’s 19 and I’m 18. Our baby is 3 months old. He’s been having bad colic lately and I’m taking care of him alone. The baby will cry till he can’t breath and my husband won’t get up from his games or Evan ask if I need help. I’m so stressed out. I have a disorder that causes me to pull my hair out (not going into detail up here but can give more info if asked for). I haven’t done it since the baby was born except I broke last night. My husband knows about my pulling issue and he still didn’t help with the baby. But I can’t ask him to help because he works and I don’t. He calls me lazy and says I sit on my ass all day while the baby sleeps. Our room is dirty because I can’t put the baby down to do anything. I have to eat with him sleep with him shower go to the bathroom or do anything with him in my arms. My mom is the only one that takes him when I’m crying my eyes out because the baby won’t calm down.
