Reached my breaking point

I have a 25 month old boy. We had help from my parents and in-laws when he was a baby but it’s just my husband and I for a few months now. My kid is a very picky eater, we r meeting some professionals about it but for now, i do what i can to keep him fed. He has been exclusively breastfed for 7 months or so and we are still continuing it along whatever little solid foods he eats.

At daycare, he absolutely refuses to eat solid food except for a few ounces of dairy milk. So on week days, I make sure he has a proper homemade dinner along with snacks and some cookies.

Weekends are difficult if it’s just him and me because he will refuse solid foods and insist on just breastfeeding. He doesn’t talk yet but unfortunately he has picked up a habit of biting me hitting my face for attention or play? I have tried to say no and put him away for a while to show him that it’s unacceptable behavior, but clearly I suck at it.

This long weekend has made me miserable. I have a minor cold. I’m on my periods and I just wanna be left alone. I still make sure I cook and feed him (which he refuses half the time). I still fed him snacks just so he doesn’t starve. I let him play on lap and he bit my face. Really hard. I snapped. I put him aside really quickly and just cried and screamed in pain. Threw some stuff in anger and just locked myself in a dark room.

I honestly wish I never had him. I suck at being a mom. I don’t know what to do right now. Any advice or suggestions?
