Hi OP. I'm sorry that you were exposed to CP. Thankfully I didn't see it before it was purged, but I'm sure it was distressing, especially for someone who was a victim.
I feel that you post is important, but this is not really the appropriate community to raise it. Can you please re-post in support@Lemmy.world?
Depends on your circumstances. I plan to start a degree or PhD when I retire just to keep the brain active.
