Self sabotage

It's really weird just watching a person live a life whilst being trapped inside it isn't it? I'm sat in this vessel not believing i'm doing these normal things like going to work when why would I? Because I doubt whether this is the real world and surely that doubt would prevent me from doing everyday things.

I keep telling myself this is the real world and there's no other world I can be in. Yet I don't believe it. And don't quite want to in a way as what if I am in a fake world and I need to get back to the right one? There's one voice telling me I have always been here and must accept that, and another telling me that I shouldn't because this isn't the real me or the real world.

So am I self sabotaging myself or do I truly believe these things?
