Feeling a sense of dread before travelling

Anyone else get like this?

I’m leaving tomorrow for Japan and I’m just feeling anxiety and a sense of dread. I’ve been having really terrible luck these days and I don’t think it’s over, I feel like this bad luck is going to follow me on this trip. I just have a feeling something terrible is going to happen and I had a will written last week just in case - this is the extent of my anxiety. I just can’t feel excitement. I’m not sure if it’s because I’ve been to Japan before, once solo and once with friends so the excitement for the country has waned. Or because it’s depression. Any ideas how to get over this sense of dread before travelling? It’s not ideal.
