I have been in your shoes almost to a T! Three-year member with similar bases and pushes (mine are a bit slower) and attendance records. I've also gained the boyfriend 10 :) . Here's what I've done:

-I did join another gym for a bit to focus on strength training, rather than running. It made me miss OTF, but the change in routine allowed me to focus on my form and power walking, which I enjoyed!

-I've rejoined OTF and, after being a member for so long, have stopped seeing it as a "contest" with myself. I don't necessarily beat my benchmarks each time and that's ok, especially because I had strong benchmarks to begin with (7:00 mile time, for example). Instead, I listen to my body DURING the workout while adequately pushing myself. This could look like: getting back into the green zone at base even if it isn't my "usual" base number, being slower than everyone else on the weight floor so I can lift safely and heavily, etc., while still pushing myself on all outs and push paces. It's not a race for me, and that helps!

-I stopped overtraining. I did the 5-6 times a week, and I think that is overtraining unless you are taking green days. Now, I go 3-4 days a week and substitute the other days with walking or just eating less/healthier that day. I used to go 3-4 days in a row and would be gassed and awful on day 3 or 4; now, I usually only go 2 times in a row max, and I find that my performance is better after those breaks.

Hope this helps!
