Hi, Anxiousguy,
I have had Anxiety and Panic Attacks since '83 and have severe Depression. I have just found in my Medical Records I have Depressive Personality Disorder - dx '89. New news to me, interesting to put a label on it, but I digress.
Above is the link to my thread Simple Meditation Technique in Social Chat Forum if I have done it right - I'm such a technophobe.
The point is, my mind is as cluttered as yours, and my body is wracked with pain, but I still benefit from Meditation. It is best to take classes, but obviously this would be hard with Anxiety and OCD.
Just start slowly with the Breathing Meditation.
Have a quiet, peaceful room with no distractions.
Sit comfortably on the floor or in a chair.
Half close your eyes.
Without changing your breathing, concentrate on your breath - the sensation entering and leaving your body.
Concentrate only on your breath, let all other thoughts drift away.
If thoughts impinge, return your mind to your breathing.
Start small. 5-10 minutes is fine, with 1-2 minutes of clarity when you have the technique is good. Build up from there.
The results last throughout the day.
Persevere.

Dave.
