Can I get into a selective college with limited extracurricular activites?

i'm gonna be a senior next year. some circumstances (e.g. moving and injuries) have kept me from doing school activites. i volunteer at hospitals since 9th grade. i help out at church events starting 11th grade. i'm doing PFEW over the summer. i'm volunteering at the YMCA starting in the summer. Can I quickly bolster it?
