Welcome to SparkPeople!
I am sorry to hear about your divorce & depression. It sounds like you are ready for the track though!
I was pretty out of shape when I started SP (about 3-4 weeks ago). I just started walking, 3 times per week, at least 1 mile. I upped this to 2 miles when I felt ready, then started adding laps of jogging in during that mile & now I am actually jogging a half mile straight (did that today)! Also, strength training has been really good to me! I feel like I am sitting up straighter and am just generally stronger! I have been swimming again (I swam in high school on the team), and it feels so good to be in the water again!
Exercise naturally creates seratonin, which keeps/makes you happy. I have noticed that I am much happier & laid back now than I was before I started a regular workout regimine.
My advice is to start off by picking a few days of the week that you can fit in at least 30 minutes of exercise at the gym. Then pick your favorite thing to do...the one thing that you can "lose" yourself in. Mine is swimming...others do well with running or walking. Focus on doing that task for at least half of the time you are at the gym. Begin incorporating other cardio machines in, along with strength training (that's so important!). Pretty soon you will start to spend lots more time at the gym because you LIKE it! You'll start to feel better about yourself!
But if you do have an illness (as was stated by the person posting previously), you will definitely want to see a doctor first!
