Spencer, It's really hard to wrap your head around the fact that the person you loved, the person who supported you in so many ways, is gone. My children are a bit older than you(both in their 20's) and lost their father about 18 months ago. One thing I've been very happy about is the way they still talk about "Papa" and mention things that he would've liked or how he would handle things. Find someone you can talk with about your mom. Try to honor her memory by doing things that you know she would want you to do...like (ok I sound like a mom) go to school everyday, do your best to become the person/adult she would want you to be. Lean on friends...and if that means leaning on the people on this site, do it!
