Loneliness

So, last couple of weeks I've been struggling a lot with loneliness. Been living alone for 3 years now. Been through enough traumatic shit. (I guess we all have) But I'm thankfull i have some amazing friends and I have the job of my dreams that I worked hard for. But at the end of the road I sit at home and feel like I have nothing and I'm all alone. And I don't know why. Anyone have the same feeling? How do you cope with it?
