Pregnant SAHM

So I have a 6 month old daughter and am currently 13 weeks pregnant. I'm suffering so bad with sickness. Im sick as soon as I wake up, I throw up when I'm about to walk downstairs. I throw up when I'm playing with my daughter. It's so bad I'm throwing up when I wash up. I have to mentally prepare myself to brush my teeth. I feel so guilty because I feel like my daughter hasn't got the stimulation she needs. She's always got something to do, but I'm always by her either being sick or having to run to the sink as quickly as I can. It's terrible. I just feel so guilty
