Does depression and anxiety attacks become hereditary?

All my siblings (there’s 5 of us) have depression and anxiety attacks. I suffered from it for a year but finally got over the anxiety attacks after learning to control it and depression gradually went away when I started spending my time eating healthy and working out. Right now, My younger brother has it really bad and my other siblings are going through it but not as bad as the youngest. I’m scared my children will go through this I don’t wish this feeling to anyone not even to my worst enemy 😔
