z,
I am not sure how experienced you are as I notice you have only been a member here a short time....I can tell you though, we have all been through these 'heart stopping' experiences and probably still do at times.....it is all a learning experience which takes time (a lot of time and effort).....the difference is, after losing a few times, you end up becoming more cautious (and hopefully, less greedy...small gains are better than no gains). I personally, would never put more money than I could afford to lose on any share, especially these 'speculative, penny stocks' even if nickel is hot at the moment.
Remember, no one wins all the time and it’s the losses that end up making you better at it in the long run (as long as you learn from your mistakes). It is also important to have a stop loss in place.

Best of luck
