You are asking at the category 'Philosophy' and not at 'Mental health', so I will answer beyond that what people call 'insane' and of course you are not 'insane' otherwise you wouldn't question yourself and ask here. In contrary, for me it es clear that you are healthier than the majority of humans on this planet.
Isn't it obvious that every thing that is in contact with humans is absolutely not healthy at all? Humanity is sick and insane as a whole and not many individuals are questioning their condition. But this is the first step to enter into a *healing process* and for this one doesn't need any professional helper, as these, - as part of the system, are more insane than those they are pretending to heal, by just eliminating their symptoms.
You are confused and so out of balance. There is nothing 'wrong' with you and it is OK that you are critical with yourself and that you observe yourself, then trying to find out what goes on. That gives you the opportunity to question yourself and do something consciously about it in a creative way. Instead of adapting yourself to the zombie like conditions of the majority.
Understand, that you are in a learning and growing process. This is at the same time a healing process! This only can happen in your daily life situations with all happenings and encounters. That is what life is about! See whatever shows up as a challenge that asks you to relate and respond the best you are capable.
If people would adapt this attitude, then they could heal themselves and with this whole humanity could go into a transformation. But people are stuck in their growing and their learning is limited to the survival need of their personalities. This condition indeed is 'insane' and causes all misery and disastrous conditions around!
Don't compare yourself with others, trust yourself and your inbuilt *growing force*.
Ask questions! Without questions, there is no answer! But ask real questions and not just those, even though these sound so intelligent, who are looking for confirmation for their established 'insane' condition!
