like many others here, it just took time.
I moved down here to PA and that was the first time that I'd been away from my family, heck I didn't even live on my own before that. I lived with and took care of my dad. That was REALLY hard for me. I would cry my eyes out at night thinking about how my dad must be home all alone eating baloney sandwiches and wearing dirty clothes cause he can't do the laundry or something like that lol. I wanted to go back SO badly. To be honest, I don't know how we made it through that first year because I was so depressed and all I did was sit around the apartment in my pajamas barely even showering and I was moody and all over the map. I didn't know at the time that I was depressed.
Then I did go back without Brian. I lived back up in Canada for a year (I had an apartment and my dad rented the extra room for me) and it was then that I realized how much I missed PA. I didn't want to live in harrisburg anymore... but I also didn't want to live in London Ontario anymore.
Now? I couldn't IMAGINE being anywhere else. Lancaster, PA is my HOME. I love it here and I could never go back to my hometown... it's not the town I grew up in anymore. Now it just seems run down and the neighborhood I grew up in is now one of the worst areas in the city. it's just not the place from my childhood.
So it could be that it just really takes time. being away from your family (especially if it's for the first time) is really hard but it does get easier. To make it easier on me I started calling my mom every single day just to chat. maybe you could call your dad everyday and make it a routine to call just to chat about your day. even if it's just a bunch of "well we didn't do much so uhhhhh I don't have much to add"... it doesn't matter
just hearing their voice helps.
