Am I too clingy?

Okay! So, my boyfriend and I have been dating for about 7 months now. When we first met, it was like love at first sight and ever since that moment we haven't left each other's side. We met when I was 15 and he was 18 now I'm 18 and he's 21 and he lives with me and my roommate. I do virtual school and I work part time as a waitress. I'm usually home most of the time now considering I've been very sick with severe anemia, and when he leaves the house I get panicky and I just tbh can't really stand it especially when he's gone he all day at times. He doesn't work because he got into a car accident and injured his back so when he goes out it's usually Doctor appts, grandmas house, favors for friends, ect as so he says. I really hate being by my self (personality issues) but at the same time I really hate when he's gone. Is that bad? Should I just take a chill pill and relax or should I talk to him about it? Idk help!
