Two Plus Two Older Archives - I need help-

Two questions that I have been dying to ask on 2+2 and now I have finally gotten around to it.
1 Topic: I have been playing poker now for 3 years at the casino level and I am only 21. I have a lot of confidence in my game. I have turend 2k to roughly 25k all in cash games. I am now currently buying into the Commerce NL 600min with blinds 10-20 and have been doing well in it. Over the last 6 months (thats when I started to keep track) I have never lost more than 3 sessions in a row. Here is where I am confused. I know that statistic is really good, but I am not sure if that statistic can stay at that level. People who play for a living, here is my question to you: what are some kind of the loosing streaks you have on. What is considered a bad streak? I am scared that I havent been on one, and the skill I think I have can all just be an allusion. What are my odds of going broke? Cause I am trying to expect the worse, but I just cant see myself loosing more than three sessions in a row.

Topic 2: I have been playing all this poker behind my parents. I am a Persian Jewish male, and as some people know, its not really accepted in my family. I feel that I can never go pro without telling my parents. I also feel that if I tell my parents, I would play smarter and make better decisions b/c I know this is my [censored] job. FOr those people who have had a similiar problem, how did you present this issue to them? What where your arguments?

I am thanking everyone for their help; these have been two issues that I have been dying to ask, but I have really no one to ask.
