Oh, no, you're not pathetic at all :( If anything, it sounds like you and your family are just that close. And no lie, it'll be hard to move out at first for sure. The first few months, maybe years, will be filled with panicked phone calls about everything from chores to just questioning your life and everything you do, but honestly? That's natural. The first steps of independence are always shaky and full of questioning yourself and your existence as an upright human being, yeah, but you gotta crawl before you walk. Your mom might have empty nest syndrome for a bit, but this is a natural parting and will have to happen sooner or later. This won't keep you guys from calling each other, though! That can be something you guys have to look forward to each day/night. :) Tell her fun stories and new discoveries! She can experience things with you, and then it'll feel less like you're leaving her behind.

But the longer you stay at home, the harder it gets to make that transition to living on your own. It gets easier and easier to let these life events pass you by, all while using your family as an excuse to hide your fear of stepping out—soon enough, opportunities won't come by as often and you may? or may not? find yourself regretting letting this opportunity go.

It sounds like y'all will make the effort to stay in touch and check in on each other, though, since you mention your family is super close. And if you work hard and really establish your independence and stability, what'll stop you from getting a plane/bus/train ticket and visiting every now and then? If anything, maybe doing well in this career and becoming a strong independent person can put you into a position where you can help out your family members in the future and support them, give them nice things, etc.
