Tips for facing the "Fear" alone

Hello all! I am about to take a trip alone for the first time since I had a very difficult trip a little under 2 years ago. The thing that made it difficult was that once things started to get intense and the lines started to blur, I tried to hold on for dear life for the fear of either losing my mind or losing my sense of self. I feel like the only answer I have to give myself is to let go and trust the experience, I've been repeating this to myself and contemplating it to point where I feel ready to take a solo trip again. I feel perfectly comfortable letting go with people I trust but alone is another story.

So share any tips you have for letting go, things that have worked for you in the past, experiences you have had or any sort of insights or anecdotes that might be related to the subject!
