How to deal with loss?

It has been over 5 months since I lost a good friend in a house fire, He was only 13. I was 14. :/ He was really close and I was the last of his friends to talk to him the night of the fire. I miss him heaps and going through old school photos is hard just knowng that I’m never going to see him again :/ I am always going through old newspapers I have kept from reports about the fire and when I see the photo of him and his old house I get really upset.
Is there anyway I can help myself feel better?
