How do you manage when you're sick?

I need some tips! How on earth do you manage when you get sick? I am pregnant, and I also have a three year old. I woke up with a horrible cold and cough this morning. We recently moved to a new country for my husband's work and I have literally no one to call on to help me. My toddler is using my head and body as a trampoline, and I'm just losing the will to live!😩 I just don't know how mums of 2,3,4,etc kids do it. Do yo have a lot of help? What's the secret to get through sickness? Hormones are a mess right now too, and I'm just crying all the time😭 Thanks for listening to my self-indulgent ranting x
