If you're bored with more than just work, you might just be in a rut. A change of scenery may seem wise, but it likely won't change how you feel — at least in the long term.
Try to expand your horizons locally before expanding them even further — the grass isn't always greener on the other side.
Is there a new park or restaurant you haven't checked out yet? If you're feeling bored with your everyday routine, switch it up: Take a new route to work, pick up a new hobby on the weekends, or stroll through a new neighborhood to see if you can find anything to inspire or stimulate you.
Even if it doesn't seem like it now, homesickness is inevitable for many following a move. It might be even worse if, once gone, you realize you haven't soaked up all the experiences you could have in your former city. New experiences are crucial to growth, but before you search for that elsewhere, make sure you've taken full advantage of where you are now.
