I have to agree with Haley. Often times we think we're lonely (which you can be) but really we miss the HABIT of the relationship. For instance, you're checking your phone every 5 minutes for a text that you would've gotten. You aren't missing the text itself, you're just so used to checking your phone. That's just an example.
Take the time to go out and try new things. Maybe there is a gym nearby that offers classes? I've heard that's a great way to meet new people. Maybe you could check out meetup.org. I haven't ever gone to one of the events but I've heard of the site. Basically anything you could possibly be interested is on there and there are groups in your area that do meet ups.
Is there something you always wanted to do but never had the time/courage? Just go check it out. I had a friend that always wanted to do Tai Kwan Do and has recently started a fitness kickboxing class and loves it.
Things won't change for you over night. I got out of a very long, complicated relationship and had to take over a year to myself before I even started dating someone. You know what? That was one of the best investments I've ever made in myself.
Good luck and I hope you get the furniture thing resolved.
