Wife thinks I should see someone but I don't know

Been dealing with depression off and on for years but I've always just... managed it? Wife brought it up the other day and suggested therapy. Part of me knows she's probably right but another part thinks talking about it won't change anything. Also there's the whole finding a therapist thing which seems complicated. Plus I don't want to use the 'mental health' label, feels too permanent or something? Anyone push back against getting help and then ended up glad they did?
