Hard feeling safe in my home now.....

So on Friday night I went about having a normal night as I usually do. While I was away from my home, leaving it locked and secured as usual, it was broken into. The individual(s) who broke in attempted to come in through a window but being unsuccessful, because of it being securely locked, they decided to use excessive force and kick through my front door that had both a deadbolt lock and lock on the knob. When I got home around 4:45 AM I walked in the house as usual and once I walked into my livingroom......my heart fell to the floor and I was instantly hit with shock and fear of the realization that my home, which to me is my safe haven, had been invaded by someone..........my privacy and security compromised. Once fear had been forced on me I proceeded to the kitchen and grabbed the sharpest and biggest knife I owned and called a friend to stay on the phone with me as I walked around shaking trying to make sure the perpetrator was not still in my home. As I'm walking around scared out of my mind, I observe that the individual(s) proceeded to go through my personal items throughout my home. Still unsure of what they were looking for exactly because after thorough checking I found that out of all the valuable items they could have taken, all they stole were a few FAKE rings out of my jewelry box. I called for a police officer to come out and check the house and I made a report of my findings. The officer informed me that a burglary had also been committed at another home that same night just one street over from mine. After the officer came and went I was still filled with so much fear. I slept gripping that knife in my hand as I tried to sleep that night. I have since slept with that knife close enough to me just in case. I cannot explain in words how scared I was and still am........it's horrifying to think that even though I prepare my home to be as secure as possible, that my safety, security, and privacy can still be violated. It is a horrible feeling........almost makes you feel like no matter what you do to secure your safe haven that a thief will make his way into your home somehow if he or she so decides. I have slept in fear since then and I can only pray that it doesn't happen again. I was thankful that the perpetrator only stole the few things of no value, and that me and my son were not home at the time it happened. I'm calling this week about getting an alarm system placed in my home in hopes that it will further secure my safe haven and keep future situations from arising.
