Do I have an anxiety disorder? Please read..?

When it starts to get dark, I start to get nervous. I check the doors and windows to make sure they're locked repeatedly, I make sure the outside lights are on and I have to know exactly where my husbands glock is (I even have an alarm set to remind me to get it from him-please no gun lectures; Its very well hidden). If I hear even the smallest noise outside my heart starts pounding and I sometimes start sweating. Numerous times I have made my husband come home early and keep him on the phone the whole way bc I can't calm down over something I heard outside. When I know it's time to get my son ready for bed. I get even more nervous and get impatient with him bc I want him to be quiet, like someone will hear him? Recently, I've been asking my husband to sleep in his room bc it makes me feel like he's safer and if my husband goes to bed first, I'll get my son in bed then try to wake my husband up to sleep with him (which he doesn't think is nesessary) so it usually causes an argument. I know I could sleep with him but I feel like I'll cause something to happen. So, after he's finally in bed I will start to clean up and by then (if my husband isnt with him) my heart is pounding and I'm in a nervous sweat thinking about leaving him in his room, bc it's on the other end of the house. I've even considered moving my husband and I out of our big bedroom and into the small bdrm next to his so I can be near him at night (but I can't sleep with him?) Any noise after dark, inside or out (wind, the train, cars especially) freak me out so bad that (this is so pathetic) I've taught my son that he cannot, for any reason, open the door bc there is a monster outside. (I'm sorry) If I think someone is coming over I get nervous and I'll hide out with my son in the back bdrm. Windows freak me out. �
