I have been exactly where you are...I do mean exactly as you described. All I did was eat and train, in between I was up to my eye balls trying to find new ways to eat and train better. Hardly ever went out, lost touch with tons of friends, ran off any girl that ever got close to me, made my family think I was nuts!
Some guys get so caught up in the bodybuilding life that they never get out. But one day thank God I woke up.
I still love bodybuilding, I still train and still eat very, very clean. I will always do that, it's the way I like to live. But I woke up one day and realized I needed balance in my life. I also realized that no matter how well I ate, no matter how hard I train that I would never see my bank account go up in any significant way. I also began to realize if I was ever going to cultivate meaningful relationships again, something was going to have to give.
Thankfully for me as I said, I woke up. Granted, I did find a way to do what I love and turn it into a career. That did make things easier for me. But the other things that I mentioned that have no become priorities are too important to me if my career choice falls.
My advice, take some time off from the gym, maybe a week, maybe two, maybe more. If you truly love the training and everything that comes with it, you'll find your way back to the gym in due time. A couple weeks of putting it all on hold is not going to make or break you in any way.
Take some time, no lifting, eat some food you enjoy, don't eat by the clock, just eat when you're hungry and eat what you enjoy. Go out with your friends, make some new ones...begin creating new meaningful relationships in your life.
Also, and this is the big one...while you're on your break from training and all of that, really take some time to reflect and think about what's the most important things in your life. Many here on getbig know that for myself I often turn to God and prayer to help me find what it is when I need answers. If you're of the same mind set, then do the same, if not, do whatever it is you do to reach that point...even though, I would recommend my way...after all, it works for me.
