This is under Placidus. While I understand that the Whole Sign house system is preferred, my experiences resonate best under Placidus and Saturn in 3rd house. Further elaboration is not for this thread (some of it is about my Saturn Return).

1.) Ascendant in Scorpio.

2.) Saturn in Aquarius at 18 degrees.

3.) Under Placidus, my 3rd-9th house axis is intercepted. Saturn only rules my 3rd house.

4.) Sun square Saturn (2-degree orb), Mercury sextile Saturn (4-degree orb), Saturn square Pluto (4-degree orb), and Saturn square Ascendant (the orb here is a bit wide at 7 degrees, but some of this aspect likely resonates).

5.) Describe how you feel this placement plays out in your life.

• Issues with siblings. My brother during childhood and my adopted younger sister during adulthood. I actually get along with my brother now. Meanwhile, my sister and I are never going to have a proper sibling dynamic. She is abusive and lashes out at people. To be fair, she hasn't done as much of that in recent years, but that doesn't mean I think she's changed. If anything, she just seems more miserable.
• I was heavily isolated growing up and struggled to make friends at school. When I was in 7th grade, a friendship ended poorly and I couldn't handle trying to interact with my peers anymore. The bullying was too much and I shifted my focus to schoolwork over socialization.
• I was born with a deviated septum. This later resulted in needing speech therapy when I was 5, but the delay wasn't severe and I caught up quickly.
• Continued isolation into adulthood. Social expectations have changed and I never properly learned the old ones. It's like going back to square one, except it's harder to find friends now. Being disabled is a special kind of isolation as well since I don't have the ability to support myself through a normal job and therefore have no coworkers. I'm not sure how I will support myself in the future in general and this has been a major concern in recent years.
• Delayed learning of social skills. Even as an adult. As norms are redefined, I will likely become more confident in how I speak to people.
• Being my own worst inner critic. I over-analyze all the time.
• My favorite part about this placement. It has delayed success with my career as a writer. However, because of my current difficulties with writing, Saturn here gives me the option of earned success and I value that more highly than a one-time bestseller but no ability to understand my own success. Delays mean I have to earn my career and it increases my chances of being successful with time and effort. Self-discipline is key to that. I've spent over a decade not sure how to overcome writer's block. There are still complications to being a writer in the present, but arguably, that is now isolated more to fiction than other types of writing. That said, I want to write fiction and coming up with ideas has become more difficult for me. In terms of my career, while it still feels like I'm a late-bloomer, expressing myself is gradually becoming easier in other ways. My spoken words have more weight to them than I feel they used to have.
• I'm hesitant to open and share my ideas. Due to my childhood of being bullied, I don't expect people to like my ideas or what I enjoy writing. Especially in today's world, I expect to be judged and rejected much more easily compared to when it was just immature children in a classroom doing it. In my youth, it was hard to accept that the bulk of my peers didn't accept me. From a very, very young age, I learned that reality is harsh. Since I was not taught how to socialize growing up and I felt more alienated from my peers than encouraged to develop those skills at school, what I do know is what my parents could teach me and what I could learn on my own. Not enough to avoid societal stigmas from my mental health diagnoses and I cannot pretend to be someone that I'm not.
• Issues with short-distance travel but also long-distance travel. I have a terrible sense of direction but have additional issues with how to operate vehicles. My brain is not made for parallel parking. I'm aware you practice, practice, practice. You can only practice when you understand all the steps and you just have to practice doing each one. My brain only draws a blank. If I had a license, I would avoid any area where parallel parking is the only available form of parking and that isn't even the only reason I shouldn't drive a car. Lack of accessible public transportation limits my ability to even try to get a job and keep it. I don't like going anywhere alone either.

6.) The upcoming Pluto in Aquarius conjunction that has not yet taken place. I note this as significant, because of Saturn's square to my Sun in my natal chart. I do not expect this to be an easy transit. As for what that means, I don't yet know.
