Therapy is wonderful if you have a good one. I recommend it, totally. They dont judge you and help you figure things out. Sometimes you just talk and figure it out on your own.
I too talk before I think sometimes, I think we all do. This has gotten me into trouble. Then I kick myself in the end.
Please remember that you are bipolar (I know other people see it as an excuse) and most importantly- Your Human. Your allowed mistakes. There is also the famous " Im sorry." "I am trying to keep my foot out of my mouth"....... or try a little humor (if that person has a sense of humor). Say something like, " will you check my teeth? I think I have a fungus in there from putting my foot in my mouth". Im one that thinks humor is the best side of life. I grew up with it and I love it.
