I seriously consider what you just wrote a valuable public service.
Not that I'm against people doing whatever the fudge they want to do w/their hair, but I think a lot of people only hear - or only focus on - the possible benefits of chemical treatments.
That said, I really am sorry for the damage to your hair! It sounds like you're really going through a frustrating time. I had some damage to my hair too recently (from box dye, wouldn't ya know) and it's not a great feeling at all. I know you already know this, but just a reminder: your hair will grow back before you know it. Now's the time to pamper it and trim out the damaged parts as your new growth comes in.
If you can tolerate it, try protein treatments too. Maybe you're already know about all these options. Just mentioned it in case you didn't
All the best and please hang in there!
