Yea no problem.

Here is my overall graph from the past 1 year. Most of the hands are from NL2, then about 20k hands of NL5 and 10k hands of NL10 (which I play currently). At the beginning you can see that my showdown winnings sucked. The first 30k hands my blue line was dropping a lot. If I show you my graph from last 100k hands only my blue line is actually better than red line.
I have improved my game a lot lately.. Here is my graph from last 10k hands at NL10:

You can see that I open looser now. I also 3bet bluff more. That way I manage to keep my red line on profit/break even. I go to showdown a bit less and that is why my won at showdown is a bit better. It is difficult to get both lines skyrocketing and most ppl have the other going up and the other going down.
You don't have to avoid playing showdowns, you just have to know what kind of hands you will call or bet OTR and when 
Fold to turn raises without top 2 pair or better (baluga theorem), fold to river raises without very strong hand because villains at the micros are very rarely bluff raising on the river. And if villain calls your bets OTF and OTT and then donks OTR, he most likely has a very strong hand.
Also think when you are betting the river. Can villain call your bet with a worse hand? If not, there is no point to bet and risk that villain is slowplaying you, just check behind 
You have only 20k hands there so no need to worry. Lets see your graph when it has 100k hands
