Is it silly?

[marloncobos]

I'm 15 and just got an actual bike, not a Walmart one or something like that. Its a 2013 GT Aggressor 1.0. So the thing is I got a Bell Sanction and just realized that I'm not going to go downhill or jump like crazy cause my bike can't do that. So should I get a new helmet or stick with this one? If I need to get a new appropriate helmet for trail which should I get? Can be more than 45 dollars cause I need to get many more things. If you could help me, I would really appreciate it.
