Do I?

I have had depression for as long as I can remember. Ive drawn about my feelings then hid them so my family wouldnt know. Until yesterday they figured out I have depression and are saying to talk to a therapist, I dont want them worrying about me because before they didnt even care. I know this is pretty stupid but Ive never talked to someone about this and Ive dealt with this myself for almost 5 years. I can still do it cant I?
