Okay no but like genuinely; I struggle so hard with my voice! It's so hard to know when to switch from chest to mix voice, and my mix is so week anyway, and the break between them still isn't fixed. I just can't sing powerfully! There's no vibrato, no belt - I will never be demi :(

someone give me singing lessons plz!
