Without giving your birth details, the predictions could not be given. Pls provide.
In the meanwhile, regarding your doubt:
Rahu entered the 11th house into the star of Aslesha and sub of Saturn. Lord of the star Aslesha is Mercury. That Mercury would have been in 8th,12th etc evil houses. Other planets also influence the events.
Now Saturn is also in the star of Mercury. Hence your natal Mercury is weak. Hence these things you are experiencing.
As Ketu is in 11th house at Birth and is in 5th at present indicates your age would be 27 or 45. Your birth would be in 1st half (below June) of that year.
