Any actual guide to supporting 1k mmr with 2v2 lanes?

Hi Guys/Gals:

I am about 1.6k MMR. I enjoy playing safe lane support(Warlock, Lion, Dazzle, CM), but there seem to be very few guides on how to deal with a 2v2 lane when I'm supporting a late game carry(Spectre, Anti-Mage, etc). Most of the guides I see for "newbies" are for 3-4k MMR where there is a solo offlaner.

What often happens:

1. I buy courier/tangos/ward/clarity/salve/etc.
2. First creep wave everyone spams spells and the lane is shoved in near our tower.
3. Now carry can't last hit without serious harass and he's forced to last hit under tower.
4. If I go and try to harass from the side, the other two go on me with stuns/slows/attacks and my carry can't do much.
5. If I stand near the tower, I aggro creeps and make it even harder to last hit besides just getting nothing done.
6. I can't pull to get xp because the lane is already shoved in.
7. I have to up courier asap because my carry can't even get to the side shop.
8. I'm useless the rest of the game and my carry is 0-2 with like 20cs @ 10 min.

Im really lost on what I can do besides trying to repeatedly gank mid or just babysitting my carry with heals and saving stun.
