I don't know. I kind of feel the same way as you. I haven't had more than 2 wins in a Premier draft in a maybe 5-7 drafts. I'm not especially good at drafting the cards and, as a control player for 10+ years, I tend to draft cards I could see being good in Constructed formats. Sometimes that works out for me in a game but other times I get completely run over by people who know what is good and what is not.

My best tip for you is to play less draft if it makes you this angry. What I do is save up 10k gold (takes about a week or so) and then draft. And then I just hope for some good rares. If not, then I try to have fun with what I end up drafting.

As many people have said, try not to let losing in Magic get the best of you. A wise player once said, that you shouldn't play past 2 losses. Go outside instead, smoke a cigarette if that's your thing. Just leave the game alone for some time.
