I gets angry for no reason... I hate myself for it...

I gets angry for no reasons... I am not like this before...
Before 2 years, I am not the same person... I am a happy go lucky guy...
Never gets tensed even for a large problem... But now i am not like my same old self...
i dont get angry with my subordinates or friends...
But i always get angry and shout at my parents... I hate this... I know I hurting the person who loves me the most in my life...I also know the reason why I gets angry...

I have money, Love everything... I am well educated and loves to take new challenges in life... Thats where the problem started...

Whatever i do to run my business, I was not able to meet success... being a positive guy... I didn't want to lose and I tried to improve my business and succeded in getting good results in the business after hardworking for 1.5 Years... i even used to sleep in the office sometimes due to work... but after the success, the client didnt paid the bills properly, so i was forced to close my business...

Some of the other guys near me, gets everything they want without even sweating... but I wanted to win with my own skill... But nothing happened to me as i wanted, even though i put my full hard work behind it...

It made me to question two things i thought the most important to life:
" Hard Work Never Fails, Fight till you Succeed"
" Trust in God and work, you will win"

Really I am in a really confused state of mind...

Can anyone help me out...
