There is an old song by The Rolling Stones, "You Can't Always Get What You Want"
Like they say in the song, and it applies to almost all of us.

"you can't always get what you want, but if you try some time, you just might find you get what you need"

Yep, that is true, and to expect you are always going to get what you want is sort of unrealistic. Demanding things, attention,will only turn others off and away from you.
When you grow up, you'll see, we don't always get what we want, and having childish tantrums only makes obtaining what we want more distant.
Try to do something to distract and/or diffuse this, perhaps,exercise,read,hobbies,clean,go for a nature walk,etc.
Even give meditation a try, search deep inside, open your mind to your negative behaviour and feelings, channel that to a more productive and positive direction.
I wish you luck with this.
