I was like that on 1st tri. But thru this process of feeling nausea, tired, etc. I told myself do one thing at a time and do it slowly. Do whats important and least important will be later. If you can get helping hand will be great otherwise do it slowly. Dont push yourself so hard to do something productive. It is just hormones in the body that tires you out. So do what you can only. Having said that if I feel energized and not tired I do as much as I can for that day. Hope this helps.
