I wasn't literally urging you to compare yourself to people working menial jobs in SE Asia or the middle east. Just trying to comfort you by saying that you're in a significantly better position and you have no reasons to be unhappy with but then again, happiness is relative. 

And yeah, you should definitely go take a run and get more involved. The result of exercising is phenomenal, not just physically but mentally, too. Taking out all your stress, frustrations on the field or the running track will significantly improve your mood, attitude and outlook in general.
