Thank you so much for this breakdown of tribulations: I am still on the second one (ep.10) and it is getting to be too long! I promised to finish this but it is difficult!LOL I hope it gets better!

This particular story line is beginning to also frustrate me which is why I came looking for information on the rest of the lives. To see how much longer this one was going to continue. Thankfully it's almost over as I took just finished ep 10.
