Do you have any evidence that these symptoms were caused by long covid and not by something else that changed at roughly the same time, like lockdowns?
Obviously I have none at all, though on online covid support groups you will find people from a range of countries that have (or have not) locked down to varying degrees - so should be pretty obviously not linked. It is so odd that people are so keen to question others long term impacts from a novel disease, when I've not seem the same effort put in to down playing the long term effects of SARs on people.
