Can you easily face another 30-40(more depending on your age)years of life without feeling overwhelmed and depressed at days that just drag on?

Do you ever think that you won’t make it through the years ahead mentally. Years of the same thing day in day out and who knows what else. Okay, there will be some fun and laughter but on the whole we all know what real life is all about. Do you ever say ” I don’t know how I can bear more of this?” Sorry for the doom and gloom but I wonder if I am the only one who is fighting this despair!
