Hard to Let Go in The Present Moment

[Raptorsin7]

I just did a 90 minute float in an isolation tank, and when i brought my attention to the present set of emotions/feelings and tried to let go, I found there  so much tension in the present moment and i just couldn't let it go. I tried to say to myself "let it go" and then see what happens, but i just felt like I was aware of the fact that i clearly have not let go fully, and yet i have no idea how to let go further.
