What should I do now I am in this situation?

I am now almost 9 months sober and I feel ok physically, I feel ok emotionally/mentally too but sometimes feel frustrated and/or angry, I kind of have these 'fantasy anger' things - I imagine what it would feel like to be angry with someone and what effects it could have or how I could vent my anger. In real life situations I am very calm and ok with people. Socially, I don't do much - I just work, study Chinese and read a lot. I also paint and this is quite a release. I don't socialise with anyone - or if I do it's quite seldom. I think I need a 'lifechange' or some great shakeup to get my life into another gear, another shift or focus. Please advise.
