Mommies I need help!

My daughter who will be 2 October, 12th.

She seems so angry/mean to me😢

Her Dad has been away for 2 months on a Ship and he comes back in another 2 months.

My daughter seems to be so whiny and mean to me about everything. She hits me and bites me and pulls my hair. If I tell her No or that's enough than she has a all out temper tantrum. She takes naps and even when she wakes up she is still rubbing her eyes and still seems tired. I am trying to bond with her and have patience but everytime I do she pinches me or starts doing something she is not supposed to do and than starts having a tantrum.

She has thrown her food on the floor since she was 9 months old and still hasn't learned, she looks at us and throws it.

Her behavior is starting to concern me, We are not around other kids so I have no idea if this is normal or not.

There has been alot of changes in her life so maybe that is why she is acting up??

She also pulls my glasses off and brakes them 3 times already!!!! The only person she listens to and is nice to is her Grandpa.

Idk what to do???? It's breaking my heart!!!

Also I feel like she doesn't know how to entertain herself or play with toys, she has toys and doesn't want to play with them, instead she cries or whines or wants to do other things she ain't allowed to do. I need help!!!
