In this situation, it's still important to prioritize safety. If your financial situation allows, you should change the lock as soon as possible. Even if someone has made a copy of your key, changing the lock will make the other person's copy of the original key useless. This can help you feel a little safer and more at ease.
If it's not our house, we can just get a new door and fix the exposed part at the same time. No need to add extra paper. And we can sort out the lock too.
If you're renting a house, you can install a bolt-type lock inside to give yourself some extra security.
If it's convenient, we can also put a surveillance camera by the door so we can keep an eye on who's coming and going.
When we get back from our trip, we can check to see if anyone's moved into the house downstairs. It might be the original owner who's come back, or maybe the house has been rented out. Either way, it'd be a coincidence if someone'd moved in during our absence.
If you think someone is following you, you can either look back or bring a mirror to see if it's really happening. This will help you figure out if it's just a neighbor who happened to go out with you, or if it's the same person following you around.
If you feel in danger or if you think someone is following you, you should call the police right away.
The next thing to think about is whether we can get some psychological counseling. The above are practical considerations to help us figure out what's real and what's not, as well as to make sure we're safe.
On top of that, we might be overthinking things and making things worse for ourselves. We can get some help with managing our emotions through counseling.

Someone has been knocking on my door early in the morning the day before yesterday and yesterday. Maybe it's because I forgot to take the key out a few days ago and left it there for a whole day. It's unsettling since I was alone and no one else was around downstairs. Lately, I've noticed lights being on which is quite odd. The doors in our building have exposed parts that should be covered with paper, but the ones downstairs aren't covered, making me uneasy when passing by. Also, the other day as I was leaving, someone followed me out right after I mentioned forgetting to remove the key, and there was someone downstairs who might have overheard.
The knocking on my door early in the morning has happened twice recently. I suspect it might be connected to me forgetting to remove my key and leaving it in the lock for an entire day. I've been staying there and haven't seen anyone downstairs. Now, there are lights left on, which is strange. Our building's doors need paper to cover certain exposed areas, but those downstairs don't have any, so I'm scared to walk past them on the stairs. A few days back, someone followed me out of the house just as I said aloud that I had forgotten to remove the key, and someone downstairs could have heard me.
I've experienced some knocking on my door very early in the morning both the day before yesterday and yesterday. It may be related to me not removing the key from the door a few days ago for a whole day. There was no one downstairs during that time. Recently, I've observed lights being left on, which is peculiar. In our building, the doors have exposed sections that need covering with paper, but none of the doors downstairs are covered, causing me anxiety when walking upstairs. Furthermore, a few days ago, I left the house and someone followed me while I mentioned forgetting to remove the key, and it's possible someone downstairs overheard.
Knockings on my door occurred in the wee hours of the day before yesterday and yesterday. This could be due to my forgetfulness about removing the key a few days ago, which stayed in the lock all day long. I was around for a while, and there was nobody downstairs. Strangely enough, lights have been left on lately. Our building's doors have exposed spots that require paper covers, but those downstairs lack such covers, making me hesitant to go by them on the stairs. Additionally, when I was exiting the house a few days ago, someone trailed behind me immediately after I spoke out loud about forgetting to remove the key, and someone downstairs might have listened in.
There were knockings at my door in the early hours two mornings in a row. It seems like it might be because I neglected to remove my key a couple of days ago and left it there for a full day. During that period, I was present, and the area downstairs was empty. Lately, I've found lights left on, which is quite unusual. The doors in our building have exposed components that should be concealed with paper, but the ones downstairs don't have this coverage, which makes me wary of passing by them on the staircase. Moreover, a few days ago, as I exited the house, someone followed closely, and I had just spoken about forgetting to remove the key, potentially within earshot of someone downstairs.
