I am half way through with lesson 4. I am doing okay with the panic/anxiety attacks. But I am so tired and withdrawn all the time. I can't seem to pull out of it. Has anyone else experienced this?

yes, me! i also got up to lesson 4 and stopped having panic attacks because the education and techniques really taught me not to panic about the uncomfortable feelings. however i am contantly exausted and it has disabled me from beign able to accomplish so much which depresses me b/c i am ambitious and cant even plan a full day without needing a nap. changing habits is a true challenge and i just want to tell u to keep going and dont lose hope, keep your head up high, and really listen to the advice and follow the homework, the homework is key in changing your negative thoughts. unfortunately i stopped the program at lesson 4 because i had a set back and now i am havign a hard time starting again, so please keep at it and u'll feel the amazing difference it will have on your life, i know i felt much better when i was doing the program and i hope to start again soon. when things seem slow just remember its hard to see ones own progress but its there. i found this great metaphor in a book about patience and it has helped me come to terms with waiting: "A child may try to help a butterfly emerge by breaking open its chrysalis. Usually the butterfly doesn't benefit from this. Any adult knows that the butterfly can only emerge in its own time, that the process cannot be hurrried."
as for your exaustion, try making only one goal this week, to go to bed and wake up at the same time everyday, u should have between 8-9 hours of sleep if u can, 9 is too much for some ppl, personally i need 9. anything else that u accomplish this week are bonus and u should congratulate yourself and not beat yourself up about not getting everything done cuz u are tired...your body will have to get used to this sleeping pattern and eventually u will feel less tired. it has really helped me. also im not sure if ur tired because ur depressed or lack sleep b/c both of those contribute but if its not that u might want to get your blood tested for hypothyroidism, i've had it for yrs and i know whenever my thyroid level is down im exausted, and actually recently i suspected my dosage was too low b/c i was so tired and i was right.
goodluck on your journey and u might want to check the forum for the full paragraph from the book, i want everyone to benefit from these wise words about patience and im going to post it right now.

Hi, those feelings of tiredness are perfectly
okay. I think that you are trying to process
a great deal of information and working on this
condition takes an incredible amount of energy
as well. I think as you go through and get
stronger, you will feel more energy. So for now,
just "accept" that you will be tired for awhile.
It will become much easier to you....like second
nature. Right now its a lot of effort. I've
actually been 8 years into this whole thing and
I look back and I cant believe my life now. Its
so different. Everything this program talks about
is very true. There is no better place for you
to be. Hang in there!

Thank you so much for your encouragement. Your loving words make my eyes swell with hope. I am so scared that I will never be better sometimes. Today I went to the hospital because I am having a lot of heart palpitations that are scaring me. Of course I know why I am having them. They go along with this wonderful condition. I have just been feeling so owerwhelmed and frustrated. I almost feel like giving up, but I know that that would not help me at all. One day at a time right? I will do my best and that is all that I can do.

I am in wk 4 & feel tired all the time. I'm not resting very well when I do sleep. Yest. I had a full blown attack when I went into my bathroom to take a bath, I actually started to run in my bedroom! My brain froze & I couldn't even remember to breath. My attack lasted 25 mns. I was exhausted & when my daughter (who is 24 & lives with me & also suffers from this), came into the living rm. I broke down & cried because I felt like such a failure! & I was angry because I froze up. But you know, I prayed & I reread all my lessons through #4, & I'm not giving up. I've lived with this disorder for 26 years along with IBS for 11 & I am so very tired of being afraid. I'm completing this program & getting my life back. Hang in there, you have alot of support right here!!
