Don't do it. And don't listen to the idiots that say do it if you feel it. You have a full life to live. Go out to a bar with a group of your friends and have fun. Trust me, it will be the best day of your life!
Life is too precious to throw away. You can do it bro! Go out and try the things in life you were to afraid to do.
I know you're kinda like "WTF does this guy know?" I thought about suicide when I was younger. I got in a really bad car accident where I could have died( highway car flipped). Not only did I stop thinking about suicide but I lived my life to the fullest and I hung out more with my friends and lived a bit more on the edge.(Not drugs or anything bad but like partying and stuff because I was a huge shut-in nerd before)
Don't throw away life. Live hard!
