I'm getting too clingy?

so I have been with my boyfriend for almost a year and it awful because I feel myself getting really clingy. I also decided to do independent study high school to graduate early, and after I switched I lost a lot of friendships. I need to know things I can get involved in or how to be social and not as clingy with him. I just know that I don't want to be so consumed and dependent on him that I loose myself, and that's what I feel happening. (disclaimer: this is not because of anything he's doing, this has to do with just me). so does anyone have some advice?
