Whoever told you that is an idiot. Please do not let them do any more readings on your chart. There is nothing indicating death or danger.
You have had Saturn opposing your large group of Gemini planets. So that can be a difficult time and stressful, etc. That cycle is over, thank goodness. I am sure it was quite a test for you. You are still here and you can relax a bit now.
You have a lot of Gemini in your chart. I think that Geminis sometimes take things too literally. So reading about Astrology and the SYMBOLS of Astrology can be confusing for the mentally logical, rational, literal views of Geminis/Virgos.
You are very young and have a long healthy life ahead of you.
For your chart, the study of Astrology could do you well in terms of exploring how you relate to others and how to be in intimate relationships. You have a large group of planets in the house of 'intimate/romantic associations.'
So there will be a focus on that in this 'young' part of your life journey.
You may also be interested in business and finance and banking etc? You could be a very successful business/strategy person.
I think it can be difficult for mutable air Gemini to be housed in a fixed water 8th house. Temptations, internal power struggles. You like transparency and truth and yet feel the need for secrecy and self protection at times.
Delving deeply into your chart, as a personal exploration, could be life changing and wonderful for you. But please do not buy into everything anyone tells you about YOUR chart. You are young and impressionable and you may attract some charlatans who will scare you and mislead you, needlessly.
You have so much curiosity and have the ability to read and research for yourself.
You are much more intelligent than you give yourself credit for.
You are still very very young. Do not underestimate yourself. I have a lot of faith in your ability to learn and grow.
