Just hang in there. Your mind and gut feeling is trying to tell you where you should be going. Try writing down "where" your mind wanders off and see if you can identify the "why". Don't worry and there is not a single programmer that cannot "concentrate". You probably got stuck in a job that demotivates you with possibly the wrong people around you. You can also try and get active with something that has nothing to do with your main work, i.e, a hobby such as photography and see if it helps.
