This is likely because (depending on your personal play style), variance is much, much higher in heads up than in other forms.
Some examples:
Winrate: 5BB/100, StDev = 20BB/100. You're going to book a "winning" 100 hands 59.9% of the time.
Winrate: 2BB/100, StDev = 20BB/100. Winning 100-hand samples happen 54.0% of the time.
In my 6m experience, 20BB/100 is a "normal" deviation. In heads up, this can easily be 60BB/100. Using that number for the examples above, you book winning sessions 53.4% and 51.4%, respectively.
The closer you are to 50%, the more you're gonna want to shoot yourself in the face. It's just a massive toll that's hard to take unless you're very good at tilt control.
By having a winrate of 10BB/100 and a 60BB/100 StDev, you're up to 56.7%, and probably will be a bit more sane.
These numbers will tend away from 50% over larger samples, as your StDev will now be measured over that larger sample and therefore be intrinsically smaller. So if you can tilt free book 1000 hand sessions consistently, this above rambling doesn't apply to you. (1000 hand sample WR of 50BB/1000 with a std dev of, say, 120BB/1000 would give you a winning 1000 hands 66.2% of the time)
