From your post you indicate you are getting back into flying. Have you had a previous experience flying that scared you? (spin training? stalling? aerobatics etc?).
If there is an area in operating the aircraft in which you feel decidedly uncomfortable it may need to be dealt with gently and with some time and exposure until you can move beyond it.
How do you feel when practicing stalling? If you are unhappy there perhaps spinning should wait a bit longer until you feel confident stalling? That is no big deal. Practicing stalling (on a gentle progression of aggressiveness) helps make for good landing skills as you get used to slow speed flight and control so it is not wasted time.
Humans are not as rational as we would like to believe. Fear can be overcome by appropriate increasing exposure that doesn't put you into a strong "out of control" (figuratively not literally) feeling.
You may know rationally the wings won't be damaged when spinning. That won't necessarily stop your thoughts unless you have become emotionally confident they won't.
That all said, having a constant (but well mastered) apprehension about what things can go wrong (and correspondingly working to mitigate those risks) makes for a good attitude to flying. And a good attitude to preflight inspections
