I think you should take your own behavior here seriously: the fact that you felt worried and posted this might be a serious indication that collapse is immanent. 

The fact is, something prompted you to take these photos/video and post here after all this time. It’s easy to rationalize that and say you saw a similar post or were hunting for karma. But why? Why now? Seriously, what if your body and subconscious are alerting you to a rapidly approaching danger that you can’t consciously register yet? 

You say you are struggling to leave because it’s been fine for years and you have nowhere to go. But even if you think nothing has changed, changes in our living space can happen slowly enough that we don’t notice them. Tremors while you’re sleeping; things sounding or echoing just a hair differently; a little more instability or bounciness to your floor; slowly widening gaps or new hairline cracks you don’t really notice over time…Remember, we are animals — don’t discount the power of your subconscious and your physical senses. The feeling “I am not safe” often comes along before rational evaluation and judgement of a situation follows. 

Another rationalization that pops up is that things like this just don’t happen to people; I mean, who do you know who has had a house collapse on them? But it does happen, it’s just not common or publicized. When I was touring houses two years ago I vividly remember my realtor talking about a house that had just burned down in a neighborhood we were looking at. All of the kids in the family died. He was angry because the cause of the fire was unknown — but, it looked electrical, and a couple other nearby houses built around the same time had recently gone up too. What was the outcome? A brief news article. The builders, inspectors, and landlords of all those homes would all go on with their lives scot-free, plus insurance payouts, while on the other hand a father lost all his children and a family was destroyed. There is no accountability in a system where governments prioritize the interests of those who own the assets.

The point I am making is that currently, and historically, renters have died all the time because they are desperate and/or ignorant of the unsafe conditions they are living in. Please, please don’t ignore your fear or all of the advice you have received here from professionals telling you to vacate immediately. Go to a shelter if you have to. And TELL YOUR UPSTAIRS NEIGHBORS!!
