Struggling with Vocal Chord Exercises

I feel really lightheaded when I breath deeply.. not sure if that’s relatable to what you’re saying though. I was diagnosed with asthma first and of course did a lot of breathing exercises and especially with long inhales I just felt like I was going to pass out which would make me freak out more. What ended up helping was short in and out breaths.

You’re not doing it correctly if you can’t breathe. Takes some getting used to, and you can only do the deep breathing like 4-5x before you get lightheaded. What really helped me was getting a scuba or snorkel mouthpiece. That helps open your mouth and jaw the correct amount. Hope this helps!
