Usually the exhaustion will start to get better once you reach your second trimester so you're almost there. All you can really do for now is let yourself get as much sleep as you need and keep eating healthy.
Apples are a good way to stay energized, that and water can help.
I was like that in my first trimester also,mine went away!! So good luck to you
I read somewhere that even taking a short walk, however weird it sounds, could actually make you feel more energized. It's worth a shot! But yes, I too would imagine that just getting as much rest as you can will hopefully keep you afloat until you reach your second trimester. Good luck!
I work nights and have the same problem. Nap when you can...i often have to choose between chores and a nap. Nap usually wins! Brief walks do help also.
I'm 12 weeks too, I usually sleep when I can.... I work full time and do a extern everyday to keep myself going.... Good luck!
