What to do during a mid hard counter?

This might be a nub question but here's the story; I was playing classic as Zed mid. I had Kat top, an afk top, tristana bot, and a jinx bot. So when we first join, I notice Lissandra, and I know that Liss counters Zed, so about the fourth level, I ask in team chat for a quick gank. Trist asks who to which I reply, "anyone who has gotten their trade done, so anyone who isn't busy please." Anyway no one comes till about level 6-ish, where kat finally decides to look at chat and come over to help me with the gank. At this point, I've barely hit like 40 cs and have my boots and the doran's blade... So I end up with like a 1/4 at level 8 and Trist assumes I'm feeding. Come level 10, My team is destroying towers while I farm because all I had was like a last whisper and un-enchanted boots of mobility. Anyway I point out in chat that we would have already had nexus if someone helped gank early game, as it wouldn't be a 3v5. Kat says that mid should be the one ganking and that top and bot aren't supposed to come down and help gank for mid. In agreement, Trist says stop lashing at your team because you suck at LoL so I just left at that point... Anyway, my question: should bot and top not help gank for mid like Kat said, even when facing counter champs? I mean I've helped gank for mid a lot and no one ever corrected my actions. Thanks in advance and sorry if I put this in the wrong board...

BTW: I didn't go afk I just shut off the laptop and fell asleep.
