I felt the same off-and-on since my teen years (I'm 50). At 35, the right antidepressant changed my life. I had to find the right doctor/diagnosis then the right medication...which took some time. But life IS worth it. I just wish I had known I was not "supposed" to feel empty and doomed much of the time so that I would have gotten help sooner. Good luck in finding peace. You are not alone.
