I considered myself to be a strong person as well, I didn't share my problems with strangers either, but I finally did see a therapist, and while I found it took a real change in my way of interracting to share these things it helped. Depression damages the brain. The patterns of our behavior in dealing with the stresses and traumas of life cannot be repaired by pills. The anti- depressants can help regenerated the damaged brain cells, so can therapy, but only therapy can teach you to use those brain cells in a more productive and healthy way.

Whatever you can do,
Or dream you can, begin it.
Boldness has genius, power, and magic, in it.
