I just screamed at my toddler

I’m having to ween myself off my depression meds for another one and it’s completely Messing me up. I can’t stand anyone and I hate hearing people speak to me. My toddler was in the back seat just being a toddler and saying momma constantly and I just completely screamed at him and I started bawling saying I hate being a mother(I don’t when I’m on meds) I feel like the worst mother on the planet and I absolutely hate myself right now. I hate who I am when I’m like this. He deserves so much better, he is such an awesome child. Idk if any one will really see this but I needed to get this off my chest.
