Joanne - it sounds like you are touching upon something core to a lot of patterns in your life, which will inevitably mean that parts of you are frightened of letting go of it because anything long term like this inevitably has identity issues wrapped up with it. The exhaustion when you hit really big and really early stuff is common, as are the tears. When the tears really start flowing, just stop talking or saying any phrases and keep tapping and breathing until the emotion subsides. It can be scary as we aren't used to dealing with so much emotion, but if you can remind yourself that it's just old stuff that's been stuck a long time coming up to be released and keep tapping, you will unload a heap of stuff you don't need any more.
Tapping in the positive is an addition to the original EFT, Patricia Carrington introduced it with her Choices Method. It's a nice way to work but not at all essential. When you get to learning it if it resonates you'll be able to introduce it into your tapping, but if it doesn't flow naturally right now don't worry about it. You are touching upon feelings that have been buried for many years and just acknowledging that they are there and allowing them to be is hugely healing.
EFT can be done very effectively by phone, so if you feel that working with an experienced practitioner might be beneficial (it could make things easier), you could work with someone in any country by phone or Skype. Continuing with someone local who makes you feel uncomfortable would definately be unproductive. It could be that he bought up some issues in you that need addressing, so if there is something there you feel you could tap on that might be another door in for you. If you don't know of anyone to contact, feel free to drop me an email and I can give you a couple of recommendations - practitioners who have lot of experience with this sort of healing and who work via Skype.
My feeling is that you would be best to work through the early childhood things (not being wanted, cot death, sunburn, bleach etc) with someone very experienced who is able to hold a space and help you to journey through this in a gentle way. I know from my own experience that working on this formative stuff can be life changing. I was fortunate that my partner was able to hold a very safe space for me to process in, he was learning EFT with me at the time. If you are in a position that you can't afford to work with a practitioner, working with a trusted friend would be another option, but I suspect that with the depth of stuff coming up, it might be easier for you to have the support of someone who has personally experienced this sort of processing themselves.
You are doing some amazing healing - I know it feels like hell when all sorts of emotions that you didn't even know were there come up - but those emotions stuck inside you are what has been driving your patterns, and once released you will have the freedom to create new patterns and it will feel incredible. :0)
With very best wishes on your healing journey.
