Being lonely is 'not good', that's what God said about Adam after he made him. So God made a mate for Adam, and soon thereafter, Adam missed being lonely! Just Kidding. Couldn't resist.
I am sorry you are lonely, and sorry to hear that your husband left you.
There are many many things you can do to help yourself. You have been praying, that's good. Also, listen to God as you study the commands of Jesus, then OBEY as soon as it is clear that he is speaking to YOU about something through the Bible.
Also, I was advised by my personal christian pyschologist to get into a divorce recovery group. My first reaction to that advice was that I didn't want to go to seminar series that was attended by a bunch of rejects. But I finally came around when I heard of a really big one put on by a really nice Presbyterian church. To my surprise, it REALLY helped to know for sure that I wasn't the only 'loser' (you're really not a loser) in the world. There were at least 100 people in the one I went to, and amazingly, it was pretty much a 50/50 split in male/female attendance. Don't worry, one of the big rules is that you must refrain from trying to get a date out of the participants of the divorce recovery group. Anyway, it REALLY did help.
Also, it you are lonely, get into a regular church sponsored small group with a mix of married and single, and let 'em know that you won't be ready for dating until about the third year after divorce, so ask 'em to hold off on tryin' to fix you up with their best friend's divorced neighbor's aquaintance. A christian small group will provide you with enough support that you will at least be able to keep your head out of the water.
Have you ever sought after an actual baptism in the Spirit, like baptism in the FIRE of the Holy Spirit? This is not weird, but it is amazing! You don't even have to go to a charismatic church service. I am not talking about speaking in tongues, although that could be part of the experience. Just keep asking God to FILL you with the Holy Spirit, he knows what you need. Keep asking him, and do so even several times a day, without giving up. Study about this yourself, in the Bible. Be patient and live your day sensitive to the Holy Spirit and Christ in you. Pray and ask, it will come. Whoa! Knowing God this way REALLY, REALLY helps!
--God Bless you!
