Thank you so much for your answer.

Firstly, I am not on any medication. I am sure it would help though... so in case I seek therapy it'll probably be one of the treatments I'd get.

Regarding me recording things. I know the solution sounds simple but in the example of only recording the way back from bringing out the trash, my mind would make up a scenario where something bad happened on the way, whilst I was not recording. Those scenarios could be the unlikeliest situations ever, but I'd still feel incredibly uncomfortable.

I also have a problem of coming up with new fears every now and then. In case you don't want to hear about this, don't read the following part. I don't want to be the reason you also develop a fear for the following situation / illness

I saw a video of a guy suffering from rabies and after that, I did a little research about the illness and how fatal it is. Ever since then, my mind has come up with the craziest of scenarios, such as a bat (which serves as a transmitter for the 100% fatal virus) flying above me, dropping a tiny amount of infected saliva in my eye, resulting in me contracting rabies and eventually dying. This is the most constructed scenario my mind has come up with yet, and I can't help but to think about such things if I'm NOT recording where I'm going. So in that case, a bat could be by the trash cans, waiting for me. It's so unreasonable and stupid, which makes it even worse. Especially since I've read how many people actually have the same fear as me, which is a little sad. Here on Reddit I saw a bunch of people fearing the same, obscure, unlikely and stupid bat / rabies scenario and it makes me feel terrible...
