blue skies,
(Love the name

)
i can preach to you until next month about the benefits of exercise in overcoming depression AND anxiety!
i have always been active, and always loved the feelings of well-being and calm in my life when i am in my routine of lifting weights regularly and running.
but let me tell you, i never thought that it would help me on the path of recovery from anxiety.
first off, YOU ARE WORTH IT!
i don't know if you are religious or not, but you are alive and you were created for a reason. Think about it...what are the chances that everything just all of a sudden came out of nowhere and instantly began to evolve into all these different forms of life, and humanity of course evolved intellectually higher than everything else (the reason why big bang theorists can never truly advise), and that is the way that it is.
hrmph. kinda depressing to think that way, isn't it?
but if you believe that you were created for a reason, by a loving G-o-d, then hope and light will begin to enter your days.
but, enough of that for right now

.
you are asking about exercise. this is something that i happen to know a bit about as i am finishing up my grad degree in phys ed, have bodybuilded(?-urk) for the past 15 years, and believe this stuff!
heck- don't take my word for it...go online...look at the benefits of exercise. look at how people who exercise regularly, are less likely to not only suffer from disease, but also less likely to develop ANXIETY and DEPRESSION. And to heal from anxiety and depression, like i am doing, the benefits are tremendous. Google seach exercise and anxiety and depression to start.
exercise is SO successful that...(keep this between you and me)...in clinical studies it has proven just AS effective OR MORE EFFECTIVE than prescription medication AND counseling.
put that in your pipe and smoke it, Big Pharmaceutical!!
but like all things...it is hard to start (something about "the greatest journey begins with a simple step" comes to mind

), and old habits die hard (much like the reasons why we suffer from anxiety in the 1st place, bad/ negative habits/ thinking).
you know what though, if you are worth it (which you are), and you were created for a reason (which you were- don't worry about why just yet, as life is a journey, not a destination- oh, i love these cliches), don't you atleast owe yourself some time with something positive?
you have probably heard this many times over, but little chemical doohickies called Endorphins are released into the blood, triggering the "positive high" one experiences when running, for instance. And believe me, they work!
It takes time, but not only do they help you feel better about life, your outlook and attitude, but they also help take the edge off of anxiety.
The best part is, you get what you give.
if you are new and agoraphobic, you don't even have to leave the cozy confines of your home.
Are there stairs in your house? You could walk stairs for 10 minutes/day 3 times/ week to start for 2-3 weeks. push-ups, sit-ups, can work wonders. are there any friends or family members who can help you? your local library may have some good exercise tapes/ dvd's that you can borrow to play in your home.
best of all, you do it on your schedule, and when you are ready. studies typically show consistent results from regular exercise within 4-6 weeks.
so look at it this way blue skies...if what you have been doing thus far makes you feel down and out, why not try something else?
don't worry and get bogged down with what type of exercise routine to follow right now, because there is alot (too much) stuff out there. Alot is good, but so much is not worth a roll of toilet paper, if you know what i mean
And perhaps the one thing that i told myself when i was at my lowest point this past march and april is:
ONE DAY AT A TIME
Read Randy Pauschs book: The Last Lecture. See him on YOUTube. YOUTube Tony Robbins to get you started with exercise.
You see blueskies, there is no "bear" or "dragon" that is waiting for you, and is going to get you (I am referring to the panic response). You create the fear. You can turn it off.
Stop feeding it and start feeding YOU.
if you have not exercised regularly in awhile (or ever), get with a friend and make a doctor appointment for complete physical. make sure that you are able to exercise (you most likely are). then, just start. get your heartrate elevated. sweat. smile and breath. with each repetition, anxiety and depression dies, and you get stronger.
my new counselor has a great adage. She told me, that when it comes to anxiety she "likes Nike".
I pondered on that for some time, but still puzzled for an answer replied: "huh?"
she told me "...just do it."
