We were recently helping out another poster with the immune stuff. It's a lot to take in, so grab a coffee and find a quiet moment. I hope it helps. I'm sorry for your losses. Many of us have needed multiple DE tries before attaining success. It's not necessarily the easy road, but you are clearly determined and on the right track.
