Swathi Sarma,
Your 8th house lord is Venus. Venus is in 9th house. Venus is in the star of Jupiter who is in 8th house. Venus is in the sub of Rahu in 4th house. So Venus has to give 3rd (communications, siblings younger to you) and 6th (litigations, success over opponents, open enemies etc) through his sub lord Rahu who is in 4th house (residence, static position). Rahu is in the star of Mars in 9th house (long distance travel, higher education, father etc). Now after blending Venus has to give about your father. He may be sick and hospitalized or to visit hospitals. He may have troubles in throat. He will be affected with lungs also. Ulcers problem is also there.
For your mother Venus gives sickness in heart or lungs. She might be affected with BP also.
You might have entered in a job during 2006-2008. You might have wedded during 2010-13. There might be some disturbances or sudden fixing of marriage.
In Venus period there might be changes in your job or you might have left it because of tensions in service.
You will postpone and delay things. Without postponement you can not finish your task. You will get frustration.
Moon sub period is good regarding your children.
Good Luck
