What can happen if i injected 30 units of bleach by accident?

Injecting Bleach?: If you did this "accidently," of course, that doesn't seem good. We are not here to judge people for having the problems that they have. With that said, it seems as though you need some help, right? Because, you could harm yourself, even accidently. So, I would say, the best advice for you now, is to seek out the right help, right away, before things turn from bad to worse. Good luck :-)

Severe injury/Death: I do not see how "BLEACH" could be injected by accident, but if done, this action could cause a very serious and life threatening injury. Call 911 immediately if Bleach was injected into your system. If you are thinking about injecting Bleach into your system-DO NOT. Call your Dr. and get medical help ASAP or call a crisis center or the local emergency dept. if you are in any way depressed.
