I just explained in some other thread about problems with "Sarp dosha" as very popular in Vedic Astrology.
You have all the planets hemmed in Rahu-Ketu axis (Lunar Nodes). You don't have favorable Mars and he is leading your planets in conjunction with Ketu in 5th house.
From January 2010, you are going through terrible phase of this Affliction and there will be no respite till 2013. So, only in 2014 and there after you could come out of trouble.
Well, it is harsh to say my friend but importance of Astrology is that it could remove our ignorance that we are responsible for everything happening with us/around us. There are many things we can't help it. So, please accept whatever is going on with your life and consider this the result of your past sins. Remember that once you are through it, learning from experience, you will start afresh and will be better person than most of us here.
If you think, I might have picked your problem then consult a good vedic astrologer, he will tell you some remedy. Although, I don't believe much in it but many claims it help.
But if I have messed up with my observations that forgive me and let some other soul help you. Thanks.
Good wishes.
