EP, walk the dog, listen to music, cook, clean, read.
Think about all the good in your life. Sometimes its easy to forget how much we actually have in our lives.
There is nothing inherently wrong I think to feeling lonely. It maybe feels negative but ah, watching the telly, relaxing, and making yourself a lovely snack or meal is hellishly great after a week of work!
It is also very very important to get some fresh air. Go out, and buy a newspaper/comic or whatever even if it is pouring/snowing/etc.
go to movies
i just find something to do...go to the movies, pat the cats, start a project, sometimes i just go to bed and hide.
Looking at my dragons bring me peace. I love soft electronic music, and tinkering with something interesting.
