Feeling a little alone

I have been in such a weird place lately. I'm out of college right now, and it's the most time I have had without a distinct plan ahead of me, yet it seems all of my friends do or at least because I can't see them constantly or be in the forefront of their mind like normal, it feels like I'm so alone. The days go by and I feel like I am over saturating my friends with my name and wanting to talk when they have other things to do. And thats normal and okay, but I miss the relationships and feeling full like I had gaggles of friends. I keep mistaking semi presence for lack of love. And It's so hard to make friends when you aren't being actively out and about and social every single day. It's almost like it's Hard for me to ignore the deafening silence when i am not preoccupied, and in turn makes me feel abandoned or alone. A.k.a. I miss my friends, and I have no idea how to make new ones to fill in the gaps.
