Trusting in Promises and Plans

I've been wanting to write about this for awhile, and I'm not sure I know where to start.

There is something that I feel God has promised me. Something more specific, that is, on top of that which He promises in His word (but not super specific). And, relatedly (almost the same thing), something that I just feel I am in many ways terribly suited for, there are so many things about me that I feel are saying that that is how I would be happiest and what I would be best at.

Yet this same thing is something that my real life has never come very close to including, and that far too often makes me feel sad and doubtful that it ever will include, even angry. I turn to God and say things like, why would You make me like this if this isn't going to happen? Why would You give me this and then not let me use it?

Then one day--probably weeks or months ago now--I've really been putting off trying to write about it--I read a story about someone who had been promised something by God and who spent years by turns waiting and hoping and expecting and giving up on getting this thing, and eventually the promise was fulfilled, although in a way different than they were expecting.

I really felt God speaking to me that day, reprimanding me (gently!) for not trusting Him more.

Stop doubting whether I am going to keep my promise to you. It may not happen how you are expecting, and it may not happen when you are expecting, but it is going to happen. Stop accusing Me of giving you gifts and then wasting them. I made you this way and I AM going to use those things. I know exactly what you have been made for. Stop accusing Me of giving you a desire for something, dangling it in your face, and refusing it to you. That is not what I am doing and it is not Who I AM.
