First, good job asking. Second, when it's time to do the right thing, including take care of yourself, what people think shouldn't be a factor. Some homes do create that kind of shame over any endeavors to address family issues, but people who have broken through to heal, didn't care, and in healthier families, they'd rather see you get better than see you pretend to be fine when you aren't. In most cases, the seeds of depression are set before the age of five. The most common cause is a broken attachment. If mom goes back to work before the age of five, or worse three, or even worse in the first year of life, it's as if the ground moved out from underneath. There is then broken trust, broken security, and broken self-worth. When memories lack words (infancy), they are stored as foundational, but too inaccessible to create self-awareness. This is also the case for generalized anxiety disorder. Both depression and anxiety have been on the rise since babies entered daycare en masse, something never before seen in the history of civilization. I am a feminist, but I know every baby needs their person, whoever that is. Their person is irreplaceable. Mother Teresa could not stand in for the parent. Their person has to an ever-present presence in their life, until they are ready to outgrow their parent (ages three to kindergarten). This is the reason why we have so many social issues developing: depression, anxiety, dependency, stalking, social phobias, substance abuse and overdoses, tattoos and piercings, suicides, domestic violence, mean girls, bullies, and shooters. I regret to tell you that thus far, graduate schools are not addressing this problem in training therapists, so you need to find someone who understands the long-term effects of broken or insecure attachments (which require attunement as well as continuity) and knows how to treat attachment trauma. Otherwise, the going treatment is medication. There is a cause for depression, so if it's not the cause I just identified, you need to do some detective work, within yourself and perhaps with interviews of family members. Find the cause and address it. Causes always lie, by the way. Healing always requires honest acknowledgement of causes, despite loyalties.
