Did you ever feel really lonely?

[nova27]

The last few months I've been going through a period of feeling very lonely. It doesn't matter if I'm around people or by myself. I broke up with my girlfriend a few months ago, and feel like I don't really have any close connections anymore where I live. I feel like most people would barely noticed if I moved. My sister passed away last year, and my parents are older and live far away. Did you ever feel very lonely, and if so what do you do to get out of it? I feel like life is kind of hopeless at the moment. I do go to a therapist as well, and it hasn't really helped...
