Well venting is fine! Everyone needs to vent now and again.
As for advice on the matted I’d say don’t let it bother you too much. You can’t really define what is a long distance relationship and what isn’t because you wouldn’t want someone telling you your ldr isn’t one. And I know, it sucks to see couples that get to see each other that often and aren’t appreciative of it but you just have to let it slide and focus on yourself. :]
Have a good night!
