Good question. My last job last five years.

Woohooo!! However during that time I was on the typical medication pinwheel, trying to find which is right for me. My roller coaster of ups and downs....(sigh). I started slipping last year really bad with tears that came out of no where at times. I was miserable more off then on. I ended up quitting a few weeks ago. ( not under the best circumstances). (I learned I was starting perimenopause and with bipoars it is worse because of our disease)
I understand the relationship as well. I find that friends come and go. (but that is life all in itself, so enjoy the moment) I have been married for 20 years together almost 22 years. I have an amazing husband that will not let go. He is awesome at that.
All in all you are living the life of a bipolar. I guess I see the pattern in my own life and try to look at the high lights. For example; " Awesome I lasted 5 years!!!" Your doing great!! One day at a time.
