knowledgebone,
NihabaAshi is giving you some great advice and, imo, you, of course, should listen to it.
However, I have not understood what the main problem is yet. You need to know that clearly, or else you'll miss the opportunity to solve it. Remember, if we don't know where we are going, any road will take us there... (but where?) So, let me try:
Is it psychological (e.g., something inside your head or belly is not working as it should and you are slow/ineffective/undisciplined/reluctant to trade?) No shame here - I made a whole bunch in 1999 and lost it in 2000 and you can understand what happened to my psychology... we all have our demons and we must face them before we get good at this. There are techniques to face that, and there has been a lot posted on this board about them.
Is it relationship oriented - like this mentor or the philosophy of the prop shop you work at? Is it your impression that they are pushing you too fast without enough guidance? I don't know much about prop shops but many people here understand them and could help you out.
Is it results oriented - like you think you have a good technique but you do not make any money off it? I know a lot about that, like many others here. There may be a path of action having to do with insisting that your mentor explain things better or be a bit more patient wrt results. But I agree with NihabaAshi that you should not be depleting your capital while learning the ropes. Take it slowly and if they are not willing to give you the opportunity to learn, find another place to trade.
Of course, there's a lot of interrelationship and feedback among these three things. But, let me assume, for now, that it is the third item above that's giving you pause. Well, here are some thoughts - and forgive me if they are too basic for you... just let me know if they hit the spot or you feel you are more advanced that that.
As I have written elsewhere on this board, this summer I am training my 14 year old son to trade. Of course he is not trading with real money, he's using one of the better (real) simulators out there, but nevertheless there may be something useful here. Being a smart kid

he went through a couple of trading books and two of the most popular CD-based techniques that one can buy out there (let me not mention names, PM me if you are interested) in 6 days.
Then, I gave him his first assignment: using a popular scanning tool, find a small number of stocks that are trending well and (sim)trade them using a simple MA crossover method. I gave him the 5/15/50 SMA and the 5 min chart, and explained some other possibilities too. He quickly ended up with the 3/5/20 EMA and the 2 min chart. In addition to those, the chart also has the 14 period ADX at the bottom, to make sure the stock is trending. He's free to set profit targets and stop losses or trade the crossovers directly or both. After two losses, stop and understand what happened and change stock. etc etc.
He thinks this is Nintendo with money on it... he's done it for 3 days this week and he's been positive (not much, but +$) every day.
My question is, what if you just did that - papertrade, use a simulator, or use Ensign's playback feature, or trade just 100 shares for just a single stock... your pick. Can you confirm that you'll be positive at the end of the day?
Increase the number of stocks - what happens then? Why?
See where I'm taking you? There is science here - locate the issue and dissect it, analyze it to its component parts to understand it. Solutions will then follow.
Suppose that after a week of doing what I said above you cannot produce positive results - then, imo, consider running. Maybe you will be a brilliant surgeon or an honest politician (now, here's an oxymoron

) but you'll have a hard time being a happy trader.
Suppose you do well at this. Great, switch to a better technique (this one is as elementary as they come) and gradually increase the odds. Keep analyzing and improving.
And don't forget what I said in my previous message - good nutrition, exercise, rest, meditation if you will, positivity in your life.
Does this make sense?
