No its not weird, so if you take it then you think the trauma thoughts will come up from the association from the past. Its possible those thoughts will come up anyway now that its on your mind. Is there an out of hours service you can ring to ask them? One Prozac in my opinion isn't going to make you feel better right now, you might need some other medication. Use your best coping strategies. Don't be afraid to ask for help if you need. Hugs.
