While you should make sure to tell your therapist about those uneasy feelings, don't read too much into them as indicative of either being trans or not loving your parents. A sense of unease regarding the topics you are worried about is one of the most common effects of anxiety issues.
I've actually found those feelings more destructive than outright anxiety attacks honestly, as they deceptive in their seeming lack of intensity. With a full on panic attack, even in that state it's obvious what is happening and looking back I could always say "Well, I wasn't thinking clearly", but with that vague unease it influences your thoughts in a way that is subtle and hard to have that definitive after the fact clarity.
On the issue of not loving your parents, I wouldn't worry about that too much either. Unfortunately, those of with OCD and anxiety issues are quite adept at compartmentalizing and putting up buffers. It is common for the result to be your unconscious putting a bit of a barrier up in terms of accessing your feelings, as a defense mechanism because you worry it will only lead to hurt and pain to care for someone, but it absolutely does not mean those feelings exist.
While this is not something a mental health professional would ever say, I think of it like this: You have probably heard a version of the saying "Crazy people don't question their sanity". Well, I also believe that "True sociopaths don't question their lack of emotion." If you truly didn't love your parents, then you wouldn't care that you don't love your parents. The truth is that while these and similar conditions can create a seemingly dispassionate and cold exterior, this is often nothing more than a defensive mechanism because we feel too much, even if we aren't always aware of it because of those same defense mechanisms. Essentially, people who don't care about others have no reason to be anxious in the first place.
