Ummm... I'm mostly with you. I guess you're right in that I do feel that some emotions are not within my control.
For example, the deep depression I felt after hearing about Steve and Sarah. I didn't feel like I controlled it. On the contrary, for several years it felt like it controlled me.
Of course, I could control my reactions to it -- to some exent anyway. But sometimes I would burst into uncontrollable tears or feel an overwhelming lethargy that just wouldn't go away.
Or, still using the Steve and Sarah example, there were times when I tried to make myself feel angry at them. But I just couldn't.
Or, using a milder example, sometimes, for no apparent reason, I'll feel blue and sad. I can control my actions. I get up, I go to work, I smile and say hello to my co-workers, I show up in court and say the appropriate things to the judge. But, underneath it all, I feel this vague sadness that I can't make go away.
