My Horrible Discipline needs help

[JDMcNugent7]

I am currently being an idiot... and having major discipline problems.

I usually play $1/2 NL 6 handed, have been killing that game for awhile now, moved up to $2/4 - killed it over just 2k hands - which i know means nothing, moved to $3/6 - only 1k hands - beat it pretty good - actually felt okay playing there and i actually have the bankroll for it now, so i guess it's not that bad that I'm playing there, but I still think I should have moved up Alot slower.

ANyway - i decide to be an even Bigger moron and play some $5/10 today for the first time, played only 100ish hands and won about 1k - which also means absolutely nothing.
then i did an even More idiotic thing and moved to $10/20 - played all of 20 hands - won $500 and left because i knew i was Way over my head and I'm positive all those guys are Way better than me.

This all kinda came out of nowhere -before this week i was happy killing the $1/2 games and all the sudden i feel like i have to move up.
There is No Way i should be playing $5/$10, $10/$20, and probably shouldnt even be playing $3/6 yet. I am very lucky I didn't lose a major portion of my roll while playing 5/10 and 10/20 and I'm glad i got out of it when i did - but what do u guys do to stay disciplined and stay at the proper levels ?
I seriously can't let myself play $5/10 or higher again for a Long time - and i feel like i'm going to have issues staying away from that game.
