I have a loaded 1st house, Saturn 25D Leo conjunct ASC 27D Leo and Mars 28D Leo. At birth I was fighting NOT to come in this world. I was born 3 months pre mature, with a heart condition,collapse lung, Pneumonia and Asthma. I weighed 2 pounds, so I had to stay in the hospital for 3months. My mother said they told her to prepare for my funeral because I would not make it! The first five years of life, I was always sick in and out of the hospital. The year I turned 9 all my health problems started to fade away. but throughout my early childhood and teen years I always thought of death. I had a lot of adult responsibilities as a teen. I was always angry about having limited amounts of food and clothes. I was also picked on for looking older then most my age. My childhood was extremely overbearing and lonely. I read this is a karma aspect.
Yikes. I think the big difference between us with having Saturn on the AC is the sign. My Saturn is exalted in Libra so it's more of a blessing to me, whereas, unfortunately, yours is detriment in Leo which is hard luck. My AC also conjuncts 0 degree Libra Jupiter which is very lucky but your AC also conjuncts Mars which shows a violent and traumatic entrance to the world.
Even though I have strong Saturn influences, my chart is actually Jupiteran. I've always felt like I'm a lucky person compared to many people, despite, I actually grew up in a very harsh family environment for a good portion of my childhood (my brother died, my parents sent me away, I came back but found out my dad was hitting my mom and then started hitting me, etc.) but during the storms, I actually had fun. I had a lot of friends, I travelled a lot, met more people, met distant relatives in distant lands, learned to connect with others and just be open. My childhood wasn't completely harsh. Majority of the roughness during my childhood vanished around 11 years old... but not completely. It came back in the awful form of early adulthood when I was 17 which continued until I turn 20.
In general, I think Saturn on the AC shows a difficult childhood no matter how it gets sliced. I think as the native grows up and becomes an adult, that native is a bit more stronger underneath because they've learned to weather and survive big struggles early on in life, which can make the person more well-adjusted to coping with harsh realities of life that most can't even begin to fathom.
BTW, here my AC aspects:
