new instrument help

so, I'm not actually the instrument type, but my biggest dream was to use an instrument and to actually enjoy playing it. now, my birthday is coming soon, and i want to ask for an instrument, but I'm having problems choosing which one, it's always between: violin, saxophone, and a trumpet. so, if any of you play any of these instruments... PLEASE HELP i really need to know which one i should choose! also i need one that is easy to learn since were i live instructors / teachers are not very available, so i might need to learn by myself.
