Parenting is hard

The last few days have been rough with my almost two year old and anytime I try to talk about it and how stressed I’ve been I get told it’s just terrible twos and it’s gonna get worse before it gets better…. My daughter can be so sweet and cuddly and she’s my world but these last few days it feels like she’s on a mission to drive me crazy she’s been really aggressive and I know she’s little and she’s going to have tantrums but in these past few days I have been bit multiple times my hair pulled my face slapped and scratched and she spit in my face and my father in-laws just watched her do it so they know I’m not crazy …. My husband’s parents keep telling me to pop her on the butt that’s the only way she’s gonna stop but I don’t believe in spanking of any kind even if it’s just a “pop on the butt” we do time outs and redirecting and I try my best not to lose my patients but I did today and I raised my voice and put her in time out but now I feel like crap because I raised my voice at my kid and all I can think is she’s so small and she’s still learning right from wrong and I shouldn’t have raised my voice
