I've been fighting depression for almost a year. My depression was caused by problems at work, isolation and loneliness due to be living abroad and a breakup of a serious relationship, all at the same time. This was and is a very deep depression, although still able to function all the joy of life seems to be gone. I've been trying a natural approach (exercise, rest, therapy, etc)  for months and I did get better after few months. However new problems at work and a new breakup have thrown me into a deeper depression. I do not feel I have the energy to face it this time. Do drugs work and if so, do they work faster and better than other approaches?

Thanks
