Take this situation;
Everyone was given ice cream at the birthday party, except for Todd. After Todd got home, he felt very disheartened that he never got the
chance to taste the ice-cream there. He really desired it and now it
left a hole in his heart.
Think of it as feeling you get after a "missed opportunity" or "missed chance". You can never have it again in your life. Now the mark this situation would give a person, is there a word for it?
I'm guessing "yearning", "longing" and "hankering" would win here (perhaps I'm actually looking for them?) Or is there a more specific word regarding that situation or feeling?

Focusing on what one is left with after the initial disappointment, your description is almost the exact definition of regret:
Although, this may not meet your needs, since regret is often used in relation to one's own actions and people forget that one can regret something that has happened to oneself. I also might not pack the punch you are looking for.
The verb, to rue packs a punch (with some added animosity):
Technically, it can be a noun, but its use, in this form, is archaic.
Oh wait, are you looking for pining?
I suppose you could also use ache, which would highlight the internal pain/anguish of the loss.
