Yes, I have been through this, and it's really not fun.
I find that antidepressants along with a combination of other more natural remedies works best for me.
I am currently on Prozac but it doesn't fix it 100% so I supplement by doing the following things:
If I start feeling sluggish, I cut down on the junk food. If I start feeling jittery, the first thing I do is cut back on the caffeine. My body seems to operate the best on more natural less processed foods, and no or very little caffeine.
15 minutes minimum daily of direct sunlight. I live in a very cloudy area so I also own 2 sunlamps which I use frequently in the winter.
Exercise every day, even just a little. I wear a pedometer and try to get 10,000 steps a day. It's amazing what difference there is between a 10,000 step day and a 2,000 step day.
Water, water, water. Staying hydrated (and not filling up on junky beverages) makes a big difference for me too.
Sleep! I know my optimum number of hours to sleep to feel my best. Doesn't mean I always get them, but I know what to shoot for. Try to get your optimum number of hours of sleep, difficult with kids, I know. But try. If you can possibly sneak in a cat nap sometimes that helps too.
I also take a multi-vitamin, but the fresh and less processed foods seem to do more for me than the multi-vit.
The type of birth control I am on does affect my overall moods and emotional stability. For instance the progesterone-based shot I am on now makes me a little grumpy and "not in the moods", but the estrogen-based patch made me feel happy and confident and on top of things emotionally. I never felt more confident and sure of what i wanted then while i was on that. If you think your birth-control might be affecting you, you can ask to change to one based on a different hormone to see what happens.
The single biggest thing that keeps me from feeling jittery and teary is managing my stress levels. I try to mostly avoid any situation that is likely to stress me unnecessarily. When something is sprung on me that is stressful, I tend to get dehabilitating migraine headaches, so I also use the deep breathing in conjunction with restful and restorative yoga poses. (Not all poses work to relax you- if you want, you can send me personal email and I can explain the ones that have worked for me.)
I also see a chiropractor, which has helped tremendously to reduce and even eliminate several areas of pain that have been caused by chronic tension and anxiety -related postures.
I know that is a long list, but it has taken me over 10 years to figure out what the right balance is for me- and I'm not 100% there yet, but the quality of my life has improved dramatically since I began incorporating those things one by one. I would suggest starting with one of those pieces of advice and using it for a few weeks before adding another solution.
And remember, not all antidepressants are the same- one may not work for you at all, one might work a little bit, or for a little while, and another may be "the answer". So be hopeful, but don't expect to get the cure-all right off the bat. I have also heard that some people have good luck with St John's Wort, but it wasn't strong enough for me.
I wish you the absolute best of luck finding your balance. I am always here via email if you want to talk more about your anxiety. I spent a good chunk of my life suffering from either high-level anxiety or low-level persistent anxiety with the occasional full-blown panic attack. Plus, near-constant depression, and horrible self-esteem. I enjoy a mostly happy and joyous life now, so feel free to vent to me, or ask questions or whatever. I am here.
