Oh, sorry to hear that. I see these two little faithful ones mean a lot to you. I would like to give you some advice, but I've never had a dog so I can relate only on the emotional level.

Regarding the relationships, sometimes, I don't really know what to write because it is not the only thing bothering me. Now it is my injury (also my passions because of it), sometimes family, studies (but that not very often). I feel like I have bad luck with meeting the right people.
In my elementary school, I was an outsider. In high school, we definitely were not a good class and these people were kind only if they wanted something for themselves. One of them is still my classmate. And the two people from there I considered my friends left my life without saying anything. I can't figure out what happened. My university/faculty uses too anonymous and online approach, you either know someone, or you don't. I love going to concerts, but either they are just to big, or my father wants to go so I have no opportunity to meet someone new, or there are not people in my age group. The band I play(ed) in consists of people in totally different age group. And I like going to see ice hockey matches, but the only people in my age group are ultra fans. And that definitely isn't my tribe. I've never felt that I belong to the group of people who were around me (more times it was because they just insulted me). When I felt like a third wheel, I tried talking to them about it. They said they were sorry, but those were just empty words. Every time, nothing changed at all.

You know, I don't feel like I have problems communicating with others or devoting my time to them. That's definitely not the problem, I can always find the time...
