Being unhappy in the moment is very much tied to gratitude. And whether or not you feel grateful will depend upon your past. If you have assigned disempowering meanings to the events and circumstances of your past then they will poison your present. The belief to adopt is that these things happened for you to help you stretch and grow.
Many will cry what a bunch of BS. OK with me. Take a look back and see where holding onto that meaning that you assigned has gotten you. What if you assigned a different and better meaning? How relieving would that be?
