It's very irrational to risk more money on the same place where you lost it, you could just invest them and wait safely till you get your loses back. Casino investment options are great, you don't need to worry since they almost never lose in the long run, you only need to pick a site with the biggest amount of players, or to be precise, their wagered amount.
1 BTC is big to lose for you. If I lost this much money, i would not get sleep. But your decision is right, stop gambling and don't chase your lose. It's very hard to get back your lost in gambling. While chasing your lose there is a chance to lose some more money. So better try to earn you are lost in any other work.
