I'm sorry, I feel like this may be entirely my fault. Please let me say that I have appreciated the information that everyone is giving. I am exploring every possibility due to my recent bad experience. Normally I wouldn't worry, just dump the idiot instructor and move forward. I have to say that finding good information about where to turn next wasn't easy until I came here. I have and continue to encourage everyone to give me their opinion and I'm sorry for my frustration -- no one here deserved that.
Really, my "raw nerve" is an accumulation of events and not just one. The diving was my "plan" to get away from the things I have been dealing with for close to a year. Last year my mom passed away -- on hospice -- in the next room. The terrible insurance company did not provide me help, my brother's found every excuse not to help, and taking care of my dad and my dying mother sent me over the edge. If someone had told my brother's would take everything my dad owned and try to have him declared incompetent before my mom was cremated I would have called them a liar, but it happened. Slowly I am getting that mess squared away.
For the scuba, my planned respite, to turn out like crap was a little like seeing the light at the end of the tunnel only to discover it was a train -- sigh. I tend to compartmentalize and deal with things one at a time and *try* not to let the totality overwhelm me. The operative word *try*. I didn't give my scuba enough thought. So "overthinking" and trying to find every bit of information was the "smart" thing to do IMHO. It's the "fool me once shame on you, fool me twice shame on me" mentality.
Thanks to everyone here, and I do mean everyone. I apologize for harshness, it was out of character. I am finding my way and able to make much better decisions because of all the information and it makes all the difference. Thank you, thank you, thank you.
