For several years I have been noticing certain trends in my life, but lately one in particular has been very pronounced.  It is this:

    Whenever I'm very interested in reading or games, a state which can last for many months, I am almost completely unconcerned with my social life.  I hardly care at all about what happens at school, and don't feel much of a need to consort with people other than my closer friends.
    However, if I lose interest in these things, a state which can also last for many months, my social life assumes a great deal of significance in my mind.  School and extracurriculars become the more important parts of the day, and I tend to worry obsessively about other people's perceptions.
     I feel that the first "mood" is definitely preferable; it's more productive, sincere, relaxed, etc.  My problem is not the detioration of my social life.  Instead, it is twofold: 1) when I'm in the first state I described, my family, and especially my mom, tend to think I am depressed and sometimes suicidal.  This creates a great deal of tension in my home relationships.  2) I often don't realize my slide into the second state until it's too late and I have already done something that makes me seem/feel very foolish.
   Anyone else notice anything similar in their own life?
