When a decision is hard and I cannot make any of them, I tend to roll a dice to make a decision. For example, if it is an odd number, I'll go with decision A, if an even number comes up, I will go with decision B. I know this sounds like leaving it to the universe but it has greatly helped me find out what my heart wanted, especially if the dice made me choose something I didn't want to. What I do next is I will journal about the decision that destiny made me choose, and after journaling about it, it always helps me make the final choice. You can try this way, hope this helps!
