Pregnancy sickness

I have a 2 year old and I am about 8 weeks pregnant with our second and for the last two weeks I have been miserable!! Anything I have tried to eat immediately will come right back up. I’m lucky if I can get a few bites. I feel so guilty that I haven’t been able to play with my toddler or keep up with housework. My boyfriend works a lot of double shifts so he’s always exhausted too and I hate asking him for help around the house 🥲 I’m just experiencing a lot of mom/partner guilt and feeling so miserable. I don’t remember it being this bad with my son and I was working my whole pregnancy and this time I will be home at least. I just want the sickness to end so I can enjoy this pregnancy and also enjoy time with my son and boyfriend. Sorry I guess this is just a rant. I hope the throwing up ends soon or at least stops being an all day thing. Also anyone else with a 3 year age gap between their kiddos? Nervous about having two kids but also excited to watch them grow together.
