While it may seem difficult and lonely at the moment, do remember that your happiness is in your own hands. If you are not able to do the things you want to do, then maybe you should "start" doing things you want to do. Do small but exciting things each day. The key here is to seriously ponder over maintaining a fair work life balance. Take some small steps and make some time for your friends and family. Cut down on activities that you think are a waste of your time (like commute, TV, excessive browsing, shopping etc). If you make room in your daily schedule for things which are equally important, you'll slowly start to see that your mood and attitude towards things will improve. And finally, always look ahead. Past is past.
