So I'm generally a very shy, anxious, self-conscious person, so I don't show a lot of emotion when I'm in public.

I'm 22 years old and I've been like that most of my life, but over the past year since I started smoking I've really come to realize how shitty it's made my life and have been working to change that and be more confident.

Now, my favorite thing to do in the world right now to relax is just listen to music and sing along. I consider myself a good singer, though I've never had any kind of lessons and I didn't take choir in high school, actually I've never really sang in front of anybody, which is the problem. I know that some people that think they are good singers are actually bad singers, and I'm afraid to sing loudly in public. I copy other voices really well, but I'm struggling to find "my voice" I never think my voice sounds right unless I'm trying to copy someone else. I sing with a lot of emotion which is hard for me to do in public.
I don't really have anywhere to go just to be myself and sing as loud as I want. My neighbor's house is right beside my room and I have a roommate, neither of which I want to sing in front of. Basically I think I can sing really good when I'm completely by myself, but I'm too self-conscious about my voice and wonder what people are thinking if they hear me.
A couple of my favorite things to sing along to are
Good - Better than Ezra
Show me a Little Shame - Ben Harper
Guitar - Cake <-- Cake is one of my favorite bands to sing to I can really sound like the guy
Time of your life - Green Day
The Joker - Steve Miller Band
Friends in Low Places - Garth Brooks
If I just want to listen to something Beck - Midnight Vultures is my favorite album.
EDIT: Oh, and I'm
amazing at Fuck Her Gently by Tenacious D

I'm not completely sure why I'm posting this, I guess I must be looking for advice, I'm really high so not being able to be myself really puts my mood down, but I'm too self-conscious to do what I want. I think being a singer in a band is definitely one of my dreams.
I'm sure I could look into meds or something but I'm poor with no health insurance right now haha.
Oh well, thanks if anyone actually reads this!
