I'm sorry you had a tough time, I've had them too, and those experiences have shaped what I am now.
There is a lot of pain and suffering in most lives, whether we use astrology to map it and predict it, or not. I am prone to worrying about my family, my planet, myself.
Pluto would be doing what it does whether you had knowledge of it or not.
Suffering arising is opportunity to develop wisdom in how we deal with it. How do we deal with pain, fear, worry, anguish, loss and other forms of suffering?
Personally, I turn to the Buddhia first in these matters, not astrology.
It sounds like you don't feel ready to cope with these things, but maybe you will feel differently one day. And that's fine, personal choice is a wonderful thing, and it would be wrong to remove that.
It seems to me that great swathes of people are not using any knowledge wisely... But I'm not the wisdom police or anything.
Do you have a permit for using that knowledge?
I have found astrology to be very useful for outlining my personal strengths and weaknesses in a way that has proved to be elusive to my pure reasoning and intuitive faculties unaided.
If you don't need astrology to get the most out of life, then why bother. No one
needs it. I don't need meditation to exist, but it helps. If astrology adds nothing to your life, then I agree, just get on with living. I'm sure that people can live meaningful and satisfying lives without it.
