Yes, I have.
My current way of coping with such thoughts is listening to them, and understanding why they appear. I have reached a state in which I know why I feel bad feelings towards people among other things and accepting those feelings.
I personally don't see mental illnesses as illnesses, diseases or flaws. I see them as states of mind towards the reality we have experienced during our lives. In a playful manner - "An experience of the current relationship between us and the world".
You can use the aid of your parents by expressing your feelings. If that doesn't feel right or doesn't work out for you, there is no shame in seeing a therapist. Eventually feelings are our own, so we need to find whichever way possible to treat them.
By the way, a nurse is no professional to count on when it comes to a mental diagnosis. A diagnosis requires 2-3 meetings with a mental health professional.
