Your health condition would have been much better in the last one year. Since Mars was aspecting your rasi for an extended period of time in the past, would have affected your mind with more stress and increased your temper. Still it was manageable until July 2016. Now Jupiter is moving on to your 8th house, while Saturn, Mars, Rahu and Ketu were in bad position. It is one of the worst combination and there is no surprise if your health gets affected in the next few months.
If you are running weak maha dasa, it may end up in creating mental anxiety, depression and other disorder. If you are not careful, you will be surrounded by bad friend circle. You may even get addicted to drinking alcoholic beverages, chain smoking and other bad habits, which can make things even worse for you. You will develop excessive interest towards gambling, that needs to be avoided.
Since you have to live away from your family for some time, can will increase loneliness and aggravate mental anxiety problems. You may have to depend on pills or anti depression tablets to get sound sleep. You will get exhausted for doing even small work. There is no fault of your physical body. But Jupiter on 8th house will drain out your energy levels fast. You need to have enough prayers and meditation to keep getting more positive energies to stay balanced on your life. Take care!
