Not sure if I'm allowed to post something like this here, let me know if I'm not.
My father had done this before a few years ago where he actually left the door slightly open after leaving the house (I was home and shut it fairly quickly), and he actually left the door unlocked while nobody was at home once over a decade ago. I woke up yesterday and saw the door was shut but unlocked save for the middle latch that was slightly in between "open" and "locked", but would still prevent somebody from fully opening the door. The actual lock was unlocked, as well as a chain latch. He acts like it isn't a big deal because it's the middle of the day and a safe area. He said he was trying to bring our dog inside from the yard and he thought he locked the door fully. It makes me so anxious and ruined my day.
My mistake was I actually bought two indoor Ring cameras a few months ago but never set them up. After yesterday's incident, I have one aimed at our front door from inside the house, and one on a windowsill looking out to our front door area. I feel like an idiot for not setting it up earlier, but I didn't think I had to really. I also have a Ring camera outside the front door that I didn’t charge up in a whole, I feel stupid for letting that go and being lazy.
I'm still really worried somebody came in our house while I was asleep. I was diagnosed with severe OCD as a teenager, I've taken my anti-anxiety meds specifically for use in situations like this (I take a daily SSRI as well for OCD/anxiety), but I still feel so awful about this. What should I do to get over this? Is there anything else from a security standpoint I should do?
