The appointment is coming up in a few days and my HA is convinced I'm walking into certain death.

What if I have an allergic reaction? Get a chemical burn? The smell of bleach fumes messes up my lungs or triggers some unknown asthma? What if a bleach covered strand gets on my face and burns me, or gets in my mouth? And then even after it's done, and I've hopefully survived, I'm probably going to be anxious about having traces of bleach sitting on my hair and getting into food or causing a reaction.

I keep thinking I should cancel but then I'm letting my anxiety win and I'll just end up miserable and disappointed in myself. I really want to do this as a sign that I'm overcoming my HA and making real changes in my life. It's important to me and I don't want anxiety to ruin it.

On a different note, I'm 90% sure I'll have a panic attack during the appointment, and probably a few after while I wait for a delayed allergic reaction to happen. Is it even worth all this extra anxiety?
