Keeki-
Sometimes I watch "self help" YouTube videos and, coincidently, yesterday I watched the video:
How Not to be Boring

The premise of the video is that we are only boring when we are afraid to be ourself. I agree with the video and am trying to learn to be a confident enough person to risk saying what I genuinely think about everything more often. LOL Because we are anonymous in this forum--this is a good place to practice. You can start threads and see how interesting they are to others. You can talk about things that are bothering you here in a relationship in order to get the support/courage (and to organize your thoughts) so you can talk summon the courage to talk to people IRL. I have done this and it helped some. I am also more boring when I am depressed because I also have a very anxious type of depression. I am a friendly, extraverted person but my last bout of depression lasted years so I became very isolated and my social skills stagnated somewhat. So, if you are depressed, getting treatment for that could help. Now that I am less depressed I have been trying to get my social skills back by calling my family more often (they are on the other side of the country), socializing at church, and being more open about my feelings with my husband. The type of things that keep us up at night, make us angry, embarrassed, etc usually are not boring. In fact--I had to respond to this thread because I can relate to the feeling of "Im not interesting to people"--so I find this thread to be quite interesting! You are not alone--I have seen others at PC express some of the same concerns.
