Anxiety and depression

I just wanted to ask if anyone else can't stand when there boyfriend doesn't text them or call them for a day or two. Like I know he has his own life and a job and shit. But he doesn't text me some days like at all. I mean before I went on vacation he was all about me. Call me everyday and come see me. I mean I know I'm annoying and I constantly text him. But It's only because I love him and I have been treated like shit before him. I know he loves me like the other day he told me he loves me and that I had better not forget it. But I think to much and I know like he's at work or he's busy but at the same time my brain won't let it rest at that. And I texted him earlier and told him I'm sorry if I'm annoying constantly messaging its just I love him And I am just depressed over everything.(oh I also lost a grandmother well my friends but it's killing me too) I just wanna know if anybody else feel the same cuz I feel alone.
