If you never ever win from the start, I suggest you to stop gambling. I think you are serious on getting your loses back but if you try to get your loses back you'll end up loses everything.  But if you still want to gamble after your past experiences then just stop for a while, take some time to think what's best to do, know your limits. Well in my experience I did invested again and ended up losing the new amount also so you should invests carefully again.
