"Struggling with grief and addiction"

I moved school and I joined a new area and new place that I've never been to I was scared and worried about the move as I never moved before. I started to find it very hard and started doing drinking and cannabis with my mates for fun and then a few weeks later my grandad passed away and I felt very upset and it effected me a lot. But I pushed through and I started going to these sessions to help me get better and I have gotten very far since I started and it makes me feel happy.
