Hello signs: Thank you for bringing your question here to PC.
I noticed this is your first post. So... welcome to Psych Central.
I'm sorry I cannot answer your question. My thinking would be that peoples' reactions to medications are so individual it would be difficult to predict what your response to Zoloft may be. Hopefully, however, there will be other members who will have some thoughts they can share.
There's a forum, here on PC, dedicated to the subject of bipolar disorder. Here's a link just in case you haven't already found it:
https://psychcentralforums.com/bipolar/
And then here's a link to an article, from Psych Central's archives, by our host Dr. John Grohol, Psy.D. on the subject of bipolar disorder. The article also provides links to a number of additional articles on the subject. Also included is a link to one additional article on the subject:

I hope you find PC to be of benefit.
