I think it’s more like everything is too overwhelming for you at this point and to make it worse, you don’t have enough rest or time for yourself (away from baby). I experienced the same thing as you, I am the main caregiver with no extra help. I get mad over the smallest stuff, over baby’s cries etc.
Make some arrangements with hubby/family, give yourself some time off away from baby.
After you’ve managed yourself, then slowly see what things are there to entertain baby, or maybe try to see what she needs. Their only source of communication now is thru crying, it will get better soon, especially when they are able to sign or use simple words. Hang in there! 💪🏻
