How to not feel scared and alone all the time

I guess it all stems off of all my friends never hanging out with me, they'll either be busy or working or cancel. My boyfriend and I are long distance and he just left after being with me for 2 weeks. Now he's on a road trip and can barely text or call me for the rest of the month pretty much. It may be pathetic but all I do is lay in my room and go on my phone. I do some things during the day, but mostly at night and in the afternoon it's all I'll be doing. Usually I FaceTime my boyfriend but now I can't for a while and I feel so scared all the time because I hate being alone. I'm used to having him by my side and now it's just me. I just wish it could be different. I don't know why I get so scared, I blame anxiety and depression. I just want it to stop.
