I generally craft a few items for myself as I level. I know I'm going to find upgrades or build new ones, so I try not to spend too much time/resources building the lower level items.
If I end up with the mats to build nice lower level stuff I either send it to an alt/auction it/ give it to a guildy.
I know being able to keep yourself geared as you level is really convenient though. I'm only level 12, so I haven't seen how this will play out in this game.
Try to stay positive and don't let something little like this ruin the game for you.
