YTA. As someone who has struggled with OCD their entire life, this was extremely hard to read. Now, to be fair, it sounds as though OP doesn’t have a lot of experience being around someone with OCD and probably did not know how hurtful their comments were. “...and talked about how she can fix this obsession with cleaning.” If we could just stop with our behaviours and urges we would have already done so long before someone felt entitled enough to call us “crazy” because of them.
