[TherapyApp] Develop a feature to differentiate gut feelings from anxiety

I'm struggling a lot right now because I'm having a huge sense of impending doom about a trip I planned. It's very uncomfortable because I am just going on with my day and get these feelings like "It's so sad this is the last time I will watch this movie/lay down in my bed" or ”I need to leave something behind before I go/finish everything I wanted to do before I go" which is very eerie and disturbing and upsetting. The most concerning part is that this feeling of "last time" does feel very calm and steady, not like when I'm actually dealing with anxiety. There's none of my common symptoms (insomnia, stomach discomfort, sore body and tension, nausea, etc.) Just a feeling of a bit of heaviness and sadness It's just a feeling that I won't come back. It's a calm, steady and uncomfortable heaviness in my chest that also feels very sad. Which is why I am very scared. It's almost like actual intuition. I have never felt this before (only the impending doom/feeling I will die soon, not the eerie feelings that it's my last time doing things) and I know it's likely anxiety — but what if it isn't? People talk a lot about listening to gut feelings, there's plenty of stories of people listening to their gut and being right, thus saving themselves and others. I'm afraid that this is a gut feeling that I'm ignoring. And I am very torn. Do I risk going to the trip trying to overcome my anxiety? Do I risk missing out on things that I want to do? It's like I'm in a lose-lose situation, and I just cannot tell each other apart.
