I usually look for some activity to do with my younger siblings (aged 11 and 9) that I used to do with my older sibling when I was their age. I'm honestly in the same boat as you right now, but spending quality time with family doing activities I enjoy is good for my spirits. Also, listening to music and groups who make worthwhile songs where the lyrics actually mean something helps too. For example, the song that comes to mind right now is Aloe Blacc's 'Lift your Spirits'. He's one artist I listen to all the time because each one of his songs has some sort of meaning I can attach to what I'm feeling at the moment.
Edit: I listen to mainly his Lift you Spirits album....not too familiar with his other albums....
