I have general anxiety disorder and get panic attacks occasionally. I took Buspar for awhile and it really helped...I just took a pill when I felt extra anxious or if I was having an attack or was having trouble falling asleep. I only needed 5mg, they are pretty strong and can make you sleepy.
right now, I am medication-free, and have been for about a month. I hate doctors and I can't stand the thought of taking medication every day for the rest of my life! So I thought I'd try and control it on my own, and so far so good! I've been exercising 4-5 days a week since August (walking my daughter to and from school, a mile each way). Exercise is supposed to be really good for controlling depression and anxiety, because it releases your natural endorphins (happy feelings LOL) I have also been able to, in the last year or 2, been able to identify my triggers for anxiety and depression. Most of mine stem from my childhood and my mother. Confronting memories of my childhood mentally, and talking about them with my hubby, good friend, and my brother; those have helped me at least understand my deep-rooted emotions and getting it out in the open helps me feel less anxious about it.
I'm also a big worrier! I will lay in bed at night thinking incessantly about the next day, what I need to get done, etc. I developed a relaxation method that has worked wonders for me! It used to take me hours to fall asleep and now most of the time I can get to sleep within 15 minutes. I focus my breathing to deep in and out breaths, and literally picture the words "IN" and "OUT" as I breathe. This keeps my mind focused on the breathing instead of everything else and so long as I stay focused I am asleep within minutes. I don't have to do that so much anymore as just remind myself to relax. It's kind-of a self-hypnosis or meditation. You should definitely try to develop a technique that works for you. When I feel panicked during the day, I do similar things, like just focusing on taking deep breaths and clearing my mind. I've also found that writing helps me release all that negative energy. I keep a blog online and that is usually where all my frustrations and anxieties go. Before, I would tend to take them out on my hubby since he was readily available to listen, but that obviously had negative effects on our marriage, so now that I can blog about my feelings, I can get it out of my system and only go to him about the important things =) Speaking of which, the support of my hubby through all this has been vital. He often helps me to relax by pointing out how funny I act when I'm panicking about certain things (cockroaches, for one LOL). He also points out when I'm acting anxiously around our kids, because that is definitely not good for them to see. And sometimes if I get too worked up and can't calm myself down, he will just embrace me in a big bear hug and not let me go, even if I try to push him away, until I can relax. My point I guess is that your hubby needs to know that anxiety and panic are REAL and he needs to support you in overcoming them, and hopefully he can work with you towards that.
Well I know this was long, but hopefully I've helped you a little, and if you want to message me to talk more about it, feel free!
