Anxiety and Sleep

So when I have anxiety I often have problems sleeping (one of my triggers if being alone at night so that doesn't help anything). I have read online that sleep aids shouldn't be used and the more exposure I get, the better I'll be able to deal with my stress and anxiety. But sometimes it gets so bad that I can't sleep. The other night I had an attack and was nauseous, shaking, sweating, and barely slept. Is it alright for me to take a sleep aid like [Edited for medication name by silentserenityy] when it gets this bad or should I just tough it out?
