The first time, yes. The second time perhaps, the third time no. Which is the normal way immunity develops in relatively healthy humans.
Damage implies something cumulative, which it isn't, unless you're immunodepressed (in which case, yes, this is Bad™).
If every time you get COVID it's as bad as the first time, you're in an at risk group. I don't have advice, but be careful.
