Coping skills go a long way, and you are by no means doomed or cursed. But there's more to anxiety disorders and bipolar disorder than simply learning to cope. Your brain chemistry actively works against any "coping skills" you may possess. Beyond this, no two cases are alike and what methods work for one may not work for another.
I don't talk about it much, but I've got PTSD and Bipolar Type 2. They take turns leaving me gritting my teeth when dealing with a crowd on a good day or making it nearly impossible to leave the front door on a bad day. To say nothing of the impact on various physical issues. And sleep? Well, the user name says it all. But I digress.
The point is that you're not alone, you're not doomed, you're not cursed, and you're certainly not hopeless. The links that Linda provided might offer some aid in dealing with the symptoms you struggle with, they may not. Spiritual methods may help, but I certainly wouldn't expect any miraculous alterations to your brain chemistry with some chanting, prayer, and the lighting of candles.
Meditation goes a long way to preparing the mind, examining your cycles of hypomania/mania and depression, and helping you be in a position where you can logically go: "Oh, wait. Everything is not hopeless. I'm just depressed. This feeling is absolutely horrid, and it's ok to cry right now. But it will pass." Affirmations and other such efforts can help you stay positive through the worst of it as well. And if you've a particular faith, well... sometimes that helps people too.
Those are just the things that you can do yourself. You can also seek medical assistance, where you will frequently be provided with mood stabilizers that assist with evening out the sway of your chemical imbalance. Many people find one that works for them and it allows them to live life like there was nothing wrong, or at least dull the edge of the mood cycles. If you're struggling with sleep a psychiatrist/prescriber may also be able to provide you with something for that.
There are numerous holistic methods for this as well, but I advise caution in this. While something like melatonin is typically quite harmless, and your doctor may even suggest it, you should consult with a professional first. Taking such things while bipolar can result in tipping the balance, so to speak, and any medication, pharmaceutical or holistic, that alters your brain chemistry even in slight ways can accidentally push you into a depressive or hypomanic/manic state.
Counseling can assist you with better understanding your cycles as well, and otherwise provide you with a great way to otherwise sort out your struggles with the disorder. And, if you've got friends and family that you're close with, it doesn't hurt to have a shoulder to cry on or a listening ear from them either. But, with friends and family, you must also understand that they can't be there always. They will do the best they can, and more often than not they'll be there, but when you're in a particularly bad state and some fluke leaves you alone with it you must remind yourself that they do love and care about you, and they will be there for you as soon as they are able.
Personally, meds didn't work. They either did nothing or resulted in fun (read as: horrible) side effects. Very little lets me sleep, and what they can prescribe is so strong that they can only give it to me in very limited doses. But through some counseling, meditation, the occasional good friend who puts up with my nonsense, and some good old gritting of my teeth, I make it through the worst of it. So can you.
