@swkstudent, Hi, I can relate to this issue b/c I'm the same. I don't think that being shy is a bad trait whether it's genetic,upbringing,enviromental, or due to trauma. In my case, think it's was due to trauma from a car accident when I was 8. Today, 8yrs of my life is still missing. I literally, had to grow up as a new person. Like waking up & being born again only you are in an 8 yr. old broken body & no Idea who you are. I grew up always afraid of almost everything. Parents weren't any help b/c they sheltered & hovered over me too much. Now, that I'm an adult & have to do things that is very uncomfortable to me b/c I was never expose to it, is my parent's undoing with the over protectiveness. I think, i'm shy more due trust, I have a hard time trusting people. I still don't trust my parents or siblings. I thought I'd grow out of it but even now I feel like I'm outside looking in when I look at my family. Ironically ,I married a very extroverted social person & was able to tolerated the people around me. I can always protect myself with his positive aura. When he passed, it was like I died instead of him. I went inward again but with my big sis's help some how I can go on even if it's like living half a life. Since, he's gone, now I have to face my fears myself & I hate it but when I do, I always feel so much better. Like I accomplished something, like winning the gold metal! I get stronger each time & what really helped me is that i got rid of that annoying behavior of worrying about what others thought about me. I also let myself be shy or let myself stay in the bat cave when I need to. When I come out of it I feel better ready to face a new day. Shy people are misjudged to be stuck up, not leader material,.... which I think is bias, I got fired from management jobs due to my shy nature. I don't consider being loud & obnoxious as good leader material.
So,don't stress over being too shy. Just be happy the way you are & when you're ready to change big or small go for it b/c it's worth it!
