Hello and welcome to the group. Staying away from social media is never a bad idea, it lets you focus on things that matter to you personally imo. I would also like to let you know that there are plenty of young people who just don’t drink or do drugs and they still have plenty of fun, the key is to find them.
When you first get sober the chemical balance in your brain is off, your brain isn’t quite use to working the way it should but it’ll bounce back with some time. There are things that can help with that depending on what your drug of choice was.
Here are some resources for you if you’re interested
Best wishes to you and your recovery
