Hello & Welcome Terry 
You are doing the best thing anyone can do and you will have to work hard but it's so worth the time and energy you put into the program, posting,journaling and so on. Many many encouraging people here to help along the new life journey you are starting. Please take your time with each session..that's how you get the most from them. Follow along as directed and you will win.
I have suffered with so many issues throughout most of my life but didn't even know how bad I was until I started this program. I am now ..just after getting through the 4 sessions doing soooooooo much better in all ways!!
Depression usually makes people feel sad, lonely, tired, some have physical aches and pains, headaches, stomach or bowel issues, and on and on. They talk about many of them on the CD's and DVD's and in the work books. You may not have as many as others or you may have different or more signs...we are all so much the same here BUT different also. 
I just was very fatigued, unmotivated, anti social, sad, sleep problems, felt lonely, low self esteem, generally very unhappy and didn't care about a whole lot. I know there were more symptoms but you get the idea I'm sure.
I also have chronic pain from Fibromyalgia since 1991 which didn't help. Add Chronic Fatigue Syndrome, Insomnia, Restless Leg syndrome, Irritable Bowel Syndrome, and other medical conditions to daily life and these all added to the depression, anxiety attacks, panic attacks, and you have me. LOL
I can laugh at it now thanks to this program and what I have learned about myself and getting the tools and skills to combat so many issues.
We all have many, many symptoms but we can rid ourselves of most or in some cases all that ails us.
My prayers and thoughts will be with you on your life changing journey as will many others. Just post if you need encouragement or start to feel badly in any way. We will help!!
God Bless, Take BABY STEPS, BELIEVE IN YOURSELF & Lucinda's program.
