If you need a psychiatrist then she was simply referring you to one she knew and likes. If she's dating him I can see how it might have been awkward seeing them together but that doesn't have any bearing on you. She's not going to avoid public events because it upsets you, particularly if her daughter is involved. You're refusal to accept reality is getting worse and LCM is utterly clueless. She would be the most helpful if she helped you find a real therapist and doctor.
