<human>: To make a long story short: I got blindsided by her leaving, she left me with all the bills to pay, all the pets to take care of, and a huge hole in my chest.

I'm still not over it just yet, but I've taken the right steps on the road to recovery so far... seeing family very often, but I'm afraid I haven't kept up with any 'friends' over the past 5 years.

The biggest hurdle I am facing right now is lonliness. I spent so many years of my life happy to be a part of something bigger than me, but it was taken away from me. It feels pathetic but I really don't know how to keep myself happy and independent. What can I do to alleviate this problem? The last thing I want to do after all this is get stuck in my head for days at a time.

Give me the gist of the text in a nutshell
<bot>: Thought I had a partner for the rest of my life. I was wrong. Need help coping with sudden lonliness.
