I am very reserved and quiet about things that really matter and bother me. I have a public persona that everyone sees which I use to cover up my deeper feelings. Everyone thinks I am a bubbly, friendly, outgoing, person--but later realize they know nothing much about who I really am, just things that anyone could know or find out. I have had issues with friends because I will not talk to them about my problems but am always there for theirs. Is anyone else like this or am I just...odd?
