The previous posters have given you some great advice. I will just add that for your generation social media makes it seem like everyone else is having the time of their lives. Instagram, snapchat, stories, etc. keep you all connected and involved in a world that is essentially just a persona. I think it makes it really hard to see that all the friends from high school have adjusted just fine. Keep in mind most of it is a crock. It’s all just an online image.
