Feeling deprived

Half way through sophomore year I moved across the country and had trouble fitting in at school, so I decided to go to online school, fast forward to now me being a senior, I feel super deprived of communication with people my age, how do I make friends being in online school and where do you guys mostly hangout at because it's kinda killing me, I go to the gym and study for college so it's not like I'm sitting in my house doing nothing, but I can never seem to come across people my age at the mall, gym, or wherever
