lol, we all cope differently but its really normal to be really fatigued i early pregnancy, i am having twins and thats def my biggest symptoms, i have never napped before in my life, until now.
Your body is very busy right now and trying to sustain your pregnancy, in a few weeks the placenta will take over and you will feel much better.
In the meantime make sure you are eating as healthy as you can
make sure you are getting enough iron too, many women are anemic in pregnancy which causes fatigue, you can get iron perscribed if you are or you can take liquid iron like Spatone, which is recommended for pregnant women. Im anemaic and take perscribed iron, liquid iron and iron in a multi-vitamin lol! im really slow to abdorb it, drink it with fresh orange juice.
Also try getting out in the fresh air and go for short walks, even if that means you come back and sleep. do you have kids already? if not maybe get out before you go to bed, you may find it wakes you up if so then great, just change the time of day you take a walk, i find i sleep so much better and feel so much more rested.
Good luck, it does get better, until you hit late first trimester when you cant sleep at all, lol!
