Robbed at Gun Point!!!  

So, about 30 minutes ago I was robbed at gun point! I was just sitting here at a friends house and two people came knocking at the door. Naturally my friend answered it. The two guys asked for some guy here and he went out side with them. My husband then got up, locked the door and went to hide his friends weed in the back. I was siting in a chair when someone tried to open the door. Noone answered so the guy said "yo i gotta pee, open the door or i'll kick it in. My husband told me to relax and stay calm. Another boy answered the door. The guy said "what are you locking the door for?" and the boy said I don't know. The guy was like wheres the bathroom and my friemd said its in the back but someones in the shower right now. Then he went back out side. My husband told me to go into a bedroom and be quiet. I obeyed and cracked the door so I could hear. The guy was asking about the bathroom still and then the showered turned off. This is where I should have paid attention. Someone started walking down the hallway and the door flew open. It was a completely different dude and he looked me dead in the eyes and proceeded to the back of the house to the bathroom. Then banging on the door he was like "hurry up man I gotta pee" and im thinking wheres the other guy? Then my friend came out of the bathroom and the other guy went it. He was in there for no lie, no more and 3 seconds. Thats not even long enough to whip it out let alone pee as badly as he said he had to go. Then he came back in the living room and asked my husband how muchmoney he had. He was like what kind of question is that and the guy was like i need some money and i want yours. Then he came in and grabbed me and brought me into the living roomand held a gunto my head and told the other guy to check my husband. My husband was like okay okay, just dont hurt her. Im balling my eyes thinking im going to die right now. Then the other guy checks my friend and takes his money too. Then he tells us that we just learned a life lesson and if my friends not carefully there coming back and he prays to god that "that pretty little thing isnt here next time". Im so scared now. Im having a panic attack and dont know what to do. They know where we live too. They said we go to the cops and it's all over. What should i do? Im extremely terrified and have nevee been through this before. Pleaase help?
