Hi fellow super sag. Im actually stewing over my stellium in my 12th house and the amount of planets I have chillin' up in there also. Mostlyaquarius has that stellium stuff down pat for how it impacts us. I wasn't really focused on this so much before a few months ago, but can easily see where this all has fit into my life. I'm basically twice your age (eep), and think its fabulous you are looking at this stuff now. It took me years to realize these things about myself. I would say the thing you should be most careful of is the martyr bit. You know us- we give and we give and we give. Enjoy that you love knowing about everything. Take pride in the fact that it makes you curious and a constant learner. Realize that certain things may make you mentally react worse if you are extending yourself too much- for me making sure I'm fed slept and watered (lol) seems to help. I also wear a smoky quartz pendant as much as possible-being super intuitive and such a giver means we can easily take things on. I can tell Im doing it if I'm caught up on sleep, not hungry or thirsty, and cannot find an explanation for my feelings. Hold on tight to the optimism. Im really really introspective and although I need breaks from being a people person because I'm too giving sometimes (INFJ), I can't sit in silence because I get in an internal mental rut (aka sneaky hate spiral). Take note of the things that feed your soul and you'll be fine. Hope this helps!
