Overwhelmed

How long does one have to carry the feelings of failure, the inability to make up for the past and the loss of strength to move forward.  I put up the front so no one sees, at least I hope they don't.

I am confident and counsel to my friends, mother to my children and parents, worker, etc. I am strength to others when they feel weak, support when they're lost and guidance....but I'm getting so tired.

The depression is setting itself in. I have traveled with this companion for years...I wish it would leave because the I'll fated thoughts and behaviors are beckoning.
