Finally told someone I'm not okay and it was terrifying

Admitted to my brother last weekend that I've been dealing with depression and anxiety for like two years. Expected him to tell me to "man up" or whatever. Instead he told me he's been on meds for five years and goes to therapy. We just sat there talking about it for an hour. It was the weirdest, best conversation we've had in forever. Why did it take me so long to just ask? Anyway wanted to throw this out there in case anyone else is scared to be vulnerable. It's actually okay.
