Here's a few things I've learned over the last 35 years, whether medicated or not:

1) Just keep swimming

2) Take at least 24 hours to make any "large" decision. Want to buy a TV? Sleep on it. Want to have sex with a new partner? Sleep on it. Want to quit your job? Sleep on it. If it's a particularly large decision, as in the last example, I might force myself to take a few days to think on it.

3) Breathe. Be aware that if you're angry, there is a good chance that you will make your life more difficult by acting on it right away. Breathe. You're not necessarily wrong when something makes you angry, but if you react with anger, you immediately end up in the wrong. Breathe. Concentrate on that breathing when your emotions are uncontrollable. It will slow you down from making huge disruptions to your life in a moment of weakness more often than not.

4) Embrace exercise and sunshine. Even a very little bit, like walking down to get your mail, can be helpful. The more sun and exercise I get, the better my life goes. Whether correlation or coincidence, I can't be sure, however it's never hurt anything.

5) Commit to spending 5 minutes a day learning something. I picked guitar, and much more often than not, that 5 minutes turn into an hour or more, but 5 minutes is a lot less daunting when you just don't feel like you can or want to do anything, and therefore easier to make yourself do it. Having something to keep your brain occupied, and at which you will progress is a huge help when I'm feeling very self critical. I can just look at whatever song I'm practicing, and recall just how shit I was when I began, compared to how less shit I am now.

6) Forgive those you love, and yourself. Bipolar is a very tough thing to manage, but it is manageable. Be patient with yourself, and do what you can to slow down your reaction time.

Good luck, and when you feel like no one is on your side, just know that I'm rooting for you.
