Have I done any permanent damage?

I vaped for like 4 months everyday. The quit. I’m worried I could have done damage to my lungs/organs and my fertility/sperm.

When I vaped I sometimes had slight problems breathing and increased mucus. Went back to normal when I stopped.
I read things about impaired sperm number with flavours like bubblegum which I used for a few days. But less with fruit flavours which I used throughout.
You should probably restore to 100% function with no permanent damage
