Sometimes I do not even know what my own reactions are to things. Does anyone else have this problem?

I learn to control my reactions by delaying them first, until i think carefully, always fearful to hurt somebody by my instant reactions...then i went too far, normalising things...i remember i didnt express my anger when my father married a woman without even telling me until 6 years later! it was stupid to feel angry and raise the subject with him after six years and my half brother was already in school.

I don't know that this can officially be considered a problem. Perhaps it just takes you time to process any given event or situation.

For me, I can take weeks to truly process a situation. It all depends on how much of an effect something has on me. If it's something that doesn't effect me personally than I may never draw a conclusion. Then of course if it is something that is really personal it can take time as well. There are various factors - but I don't personally believe it is a problem. Reacting quickly is overrated.

Do you have a specific example you are willing to share?

Of course
some things we have never faced so we have no reaction at all.
some things are so profound that the reaction goes sevral diffrent ways. we couldn't answer it correctly without writing a book
