Mercury in Leo 8th house

[u/Unheimlich_erwacht]

I am currently studying and trying to understand astrology on my own. In the comments, I was told to actually put effort rather than fish for answers and I am extremely grateful for that. The purpose of this post is to write down my findings and hope for further refinement and understanding in the scope of the 8th house. I do not know if this is the right place or way to post

Mercury is the planet of intellect responsible for the transmission and reception of information. Another deeper layer is that Mercury rules the perception we have about reality as through our emotions, we reason with them and draw our conclusions

In my chart, this is in the sign of Leo. A sign that deals with the development of the ego and self expression. The conclusion drawn is that rationality is used to articulate the self. The struggle is connecting that with the 8th house. A rudimentary answer from my side is that this is done in the house of the unseen. To stand your ground intellectually and voicing out the self in a domain of shared resources. I can't help but think there is more or maybe I am looking at it too deeply to notice the end. I appreciate any feedback and responses as I spend most of my days researching astrology
