I feel so fukkin crappy..

Im sad. Been crying the morning through.
I got a letter from my sister (who I havent seen for years).
The thing is that our father died some years ago and left a house for us. Its not a fancy or even valuable house, but its my fathers chilldhood home and I grew up spending the summers there.
After he died Ive been there once, couldnt stand it. Everything reminded of him. My sister does not ever want to visit the place.
So she wants to sell her part.
She can legally force me to sell if I dont want to buy her share, which I cant.
Dont have the money. And I dont know if my mom wants to keep it.
I feel like if I sell I will be letting my father down, but what am I going to do with a house that I cant stand visiting?
And this is really not about the money, since its not gigantic sums were talking about.
And why is my sister doing this to me? So much for all the beloved ideas of family.
I dont know what to do.
It feels like its just going downhill with everything.
Why am I writing this?
So you know, mostly.
So you understand why I am asking for you to support me right now.
So you know that even though I care about you a lot, right now Im gonna have a tough time showing it or even supporting you.
Is it gonna be ok?
