Had an intense, fun night drinking with someone I consider my best friend the other day.  We shared quite a few intimate things about ourselves while talking.  Not sure how I feel about it now which reflects a deeper issue I could use advice with.  My friend circle has dwindled significantly over the last few years for various reasons, mostly not making new friendships and people moving, and this person who was always a close friend, has become like a best friend to me and frankly one of my only friends.  At the same time, I've felt very insecure in the relationship on my end and unsure about their feelings towards me.  I'm constantly second-guessing myself and them in my head.  Am I oversharing?  Am I too needy?  Are they mad at me?  Do they feel the same intimacy I do?  Do we bring out the good or the bad in each other?  Where are the boundaries?  These thoughts are so overwhelming at times, I really can't tell my feelings from the objective reality.   I'm often afraid of losing their friendship and I often hold back a lot on my end because I'm afraid of expressing my too intense feelings.  But then a night like the other night I feel like I overshared myself and was being needy and  was just being humored, but that could just be the self-loathing!  What's the line between the subjective and the objective here?  What to do?
