Your measurements are about the same as mine and I wished I would have started PE when I was 18. You’re in luck by the fact that you are 18 and have plenty of time to work on it while you’re young and getting ready to start out being sexually active. (although you may be already)
As far as being depressed over it I can tell you that it’s not really worth it. I thought about it a lot when I was your age but never really did anything to try and change it. I actually think that I got so caught up in it that I did not do some of the things in life that I wanted to do because of it. I was always afraid of the other guy being bigger than I was so I sort of removed that equation from my life by just not doing something that may involve other males seeing me penis or being compared to other males. I wanted to do things like sports and such but never would for the fear of having to change or shower in front of other guys. I also had a lot of chances to have sex when I was younger that I passed up because of the fear of being compared to others. Don’t let yourself get caught up in that. Don’t worry what the other guys have between there legs because I have discovered in life that I am not alone and a lot of males are in the exact same shape I am in as far as my equipment size goes. Just enjoy life and don’t let yours revolve around the size of your dick. ;)
Good luck with your endeavors to increase your size.
