So nira19, if you know how to read a horary chart, how did you answer your own question?
Although I do not personally believe in the reality of witchcraft, many people did in Lilly's day, and many people in India and other parts of the world believe in it today. I am willing to take your question at face value, because your question more fundamentally is about the possibility of a secret enemy, which is a more conventional 12th house matter. If you believe that someone is applying black magic towards you and you don't know who that person is, then s/he would equally be a secret enemy.
As I mentioned above, Saturn (you) and Jupiter (ruler of the 12th) do not aspect one another. Jupiter has long since separated from its last aspect to slower-moving Saturn. We can count reception, mutual or otherwise, as a contact, but it isn't strong in this chart. Although Saturn is in Jupiter's sign, Jupiter is in the sign of its fall in Virgo, and Saturn does not swap essential dignity with Jupiter.
We often find conflicting testimonies when we look at a question in detail, but even so, the preponderance of evidence of this chart argues against witchcraft, in my opinion.
According to J. Lee Lehman, The Martial Art of Horary Astrology, Lilly gave several additional indicators of witchcraft: ruler of the 12th house in the 6th house, ruler of the 6th in the 12th, ruler of the 12th in the 1st, ruler of the first in the 12th, ruler of the 8th in the first, ruler of the 1st in the 8th, the same ruler of the 1st and the 12th, ruler of the 1st "unfortunate" in the 12th.
The one indication according to Lehman's summary of Lilly that this chart has, is the ruler of the ascendant combust. But I take this to be only one testimony in favour of witchcraft/secret enemy, and the preponderance of the evidence saying that your suspicions are incorrect.
If you believe that the religious practices and remedies you applied did not solve the problems, within your cultural framework perhaps this is another kind of evidence that the root cause was never black magic, but something else. So if you think through the potential alternatives to black magic that could be causing your problems, these are probably sensible areas to consider.
But suppose I am mistaken and you are correct about black magic as the root cause of your problems. Your considerable feelings of stress that do appear in this chart are simply adding to your miseries. You do have some control over your emotional state, and if you have problems to solve, you will do a better job of solving them if you can stay calm and rational about them.
