Am i truly in love with my boyfriend?

Ok so, whenever I'm with my boyfriend and my friends, I like spend my whole time with my bf. And when we make out, or kiss, it makes me sosososo happy, like makes me speechless/ breathless. Whenever I'm not with him i get sad, and cold. Like something is missing, and when I'm with him I'm like trying sossooso hard to keep control. I'm almost 17 now, and we've been dating for 7 months. Please answer(: thanks! ~adrienne~
