Can't sleep.

So I'm sitting here on my phone, laying in bed. My anxiety is so damn high. I took my dose of xanax at 11 and it did nothing. I practically begged my husband to stay up with me but he's exhausted so he's asleep next to me. Some starting back on my Prozac I've noticed a difference in the patterns of my anxiety, the panic doesn't happen as often. I'm usually always anxious though. Today I went to best buy with my husband and son to get my new phone. I was there for 2 hours and was anxious but no panic which is very unusual. I would always have my husband by my side and not let him leave. Today I let him go wander off in the store, leaving me alone there. I didn't want him to. I just told him to check back every 15 minutes or so and if I wasn't here that means I freaked out and went outside. So it still haunts me everywhere I go. 
Nathan is stirring in his crib. I really hope he doesn't wake up. I just want to lay here and not move. Bet that wont happen though, he seems to be lightly sleeping. OmgI wish I could just stop freaking out!!!!!!!
