Firstly, happy birthday! Secondly, I haven’t seen the transitions as all doom & gloom—while it has been uncomfortable in my own experience, it has also been transformative and powerful in terms of my own emotional growth.
If the Pluto transit is happening in your first house, it might affect the way you express yourself and how you see yourself. You‘ll be letting go of old self-images or old habits that are no longer serving you so that you could evolve into a better version of yourself.
Saturn, on the other hand, will likely affect your relationship with possessions, finances, and self-esteem. You may be more disciplined with your finances like saving more money for the long-term, or (in tying it with the first house) setting boundaries in what beliefs you have and what others are trying to impose upon you about yourself.
I hope this answer has been insightful and helpful in reframing what everyone else has been saying about these transits. Godspeed 🙂
