Anxiety attacks..

So, I'm twenty, got my own little family, an almost four month old baby boy, and my fiance. We live on our own. & I'm absolutely terrified of me neighborhood. Like, my fiance leaves early in the morning for work. & at first I was okay, but now that I have the baby, I'm so scared to sleep when he's not here. So I wake up at the ass cracked of dawn, and stay up until around 9:30 ish at night. & the only days off that he has, I work. I'm becoming a stay at home mommy full time very soon! So I'll sleep when he's off, instead of doing the same schedule, just being away from them. But my question is, how do I get over the anxiety? Like I've heard people actually hitting and playing with the doors and stuff, right after he's left. & I don't want to go back on the anxiety meds because I'm breast feeding & because they make me a sleeping zombie. I just really need some help! I have no friends or anything over here.. & we've lived here almost a year. I'm just scared to sleep the past two months..

Please don't be rude, or say that I need to grow up. Anxiety is something I've been battling since I was 8.
