Trying To Find My Motivation!

I am not a person who blogs. I have been a member of Sparkpeople for over 3 years and haven't posted a real blog yet. I'm pretty shy until I really know people so I know I will second guess everything I write. This is going to be hard for me to do but I think it is something I need to do to get some help.

I originally lost 45 pounds before joining SP and have used the site to help me maintain my weight loss and keep me motivated. Unfortunately, over the past year my motivation has deserted me. I have had some starts and stops along the way where I think it may be back but then it is gone again. I do pretty good with staying on track with what I am eating it is exercise that I am having a problem with. I have gained 10 pounds back over the last year and it is really getting me down.

I had thyroid surgery at the beginning of November so right now the only exercise I am allowed is walking. I am so ready for a long run but I don't think my incision site is ready for that yet. I have an appointment with my doctor on the 13th and my hope is that I will get the okay to run and strength train again.

I just signed my whole family up for the Warrior Dash in May. I am hoping this will be the catalyst to get me back on track.

I know what the problem is and what needs to be done. I guess I just need some help getting my "Spark" back again. Any advice would really help.
Thanks!
