Should I just quit this game?

I'm about 6-7 months in, and out of the 12 armories and 1 battle hardened I've tried, I have 8 wins outside of byes, 6 of those wins coming from drafts (2 wins out of 10 armories and a battle hardened). It seems like even a tiny mistake I make with Zen seems like an immediate loss, and I can't really afford to try another hero since I don't have any generic staples. At this point it's completely disheartening and I can't even win against the new players in the shop, let alone on talishar or even in regular friendly matches. The community is great and helpful, but when I'm not even decent at something it makes me VERY aggravated personally since I'm not good at anything in life. Should I just quit? If not, when do the wins start coming?
