Welcome to HW, you will find support here. I am Bipolar II; but was initially dx'd with depression like you. I was dx'd with Bipolar almost 2 years ago. Bipolar I would say is a bit tougher to manage, with the meds, than depression. In my opinion. It just seems a lot harder to find the right combination, and most of the time that means no anit-depressants b/c they can cause hypomania or manic episodes.
There is hope though. It's just a matter of finding the right ones; and that means really waiting those first several weeks out when trying new meds to give them a chance to get past the side effects and to start working for you.
I hope you have a good pdoc, and hopefully you have some therapy or counselling too. It's much more than just meds. I am sorry you are going through such a rough time right now. It's so hard, and we all understand. Keep posting, let us know how you are doing on your new meds. When you are sad, reach out, we'll be here.
