Make 3 friends.
Be funny, sociable, direct, what have you.
And let them know you're struggling a bit. And that you're looking for a solid group/pointers.

Either you want to improve and not be a burden (in which case, congratulations and I already like you), or you're better suited to an offline game where you can play as you want without it interfering with other's time (which is perfectly fine).

Also, check out the guides online that will give you ideas of what your role is and how best to use your skills. Will help you immensely.
