InfernoAvenger,
At my age ... I am almost your grandfather (insert Darth Vader breath hiss here).
I make a point to take new players and teens 'under my wing' and help them out. (Even when I'm the DM.) The most fun I've had at table is when a new player has the 'light bulb' over their head blink on because they 'get it' what D&D is supposed to be, or they tried something and it worked !
As a player, I've been known to alter what I would normally do so I can set up the new guy for a successful shot at what his character does best. (Ex: my Paladin to newbie Rogue "Run up to this monster I'm standing beside, whack it and add your Sneak Attack, then duck behind me. If he chases you, I'll whack him for his efforts." The Rogue did more damage to the monster than I did. And I complemented her for it.)
In most cases, adult players want 'kids', 'teens' and new people to succeed, have fun, and come back. Let the group know that you are looking for a mentor, and somebody will accept you as their apprentice. I have no doubt, though, that you will soon grow through the role and be confident in your own skills.
