Hey Kimmy Dawn.........it sure can be difficult when that kind of thing happens, but it sounds like you have put alot of time into T and its paid off. There may always be things that come up, but its all about how you choose to deal with it. I have been in T since '94 and am currently onto my 4th T - wow sounds a bit dodgy when I say that, but I've usually done a few years to a year with each and when the time has been right I have ventured away. When the time is right again to pick up some more work, I just resume. Each T has offered me something different and have worked in completely different styles, but have gained something from each of them.
I usually just tell myself that 'its ok' when I discover something that I previously had no awareness of.........there is something to be said for self nuturing and reinforcing to selves that its ok.
Take care
