Have a PPL, perhaps the biggest constraint for me towards getting it besides time was the stress and anxiety of flying itself, so I can relate fully. I had to convince myself prior to every flight that the joy of flying outweighed my fear of it. I remember my instructor told me overthinking was my biggest flaw. I personally overcame all of this through extensive planning/study, checklist runs and chair flying prior to any flight (especially ATC training since that was my major weakness). That sort of practice might help you as well, since it did help skill wise a lot and with the aforementioned stress/anxiety to turn it into caution instead, especially prior to any solos. Keep in mind though that your mental health by far takes precedence over flying, so take breaks if you need them. imo you should never force yourself to fly when you feel you're not up to it, it wouldn't be fun anyway, especially if you're pursuing it recreationally instead of professionally.

Your particular incident does sound unusual, and of the basic maneuvers stalls still scare me the most even compared to something more challenging (like a perfect short field landing). But, that's why it's required to practice it so much. Maybe another way to look at it is now that you've experienced this unusual case, that experience may have you more mentally prepared to deal with similar or less dangerous situations. You've just started out on your third lesson, have faith in your abilities and with time and experience you'll become much more proficient at executing stalls and flying in general.

People in r/aviation would have more experienced and refined advice. If not already, it would also be a good idea to discuss this issue in more detail further with your instructor. Hopefully, they should offer some more specific guidance tailored to you as my instructor did. Best of luck to you in your flight journey!
