First off, I take an antidepressant daily. Among my friends with mental health struggles, most suffer from depression. Some take medication but most do not. Most do not go to therapy. I am aware of my depression and I usually take a break people when I'm depressed. But sometimes being around people can cheer me up. Sometimes, it can depress me more. That's usually when I go to an event with a lot of people. Within the last three years, I made a friend who has admitted to being bipolar. I immediately knew something was different and possibly difficult about this person but, over time, interacting has become even more difficult. I've never known anyone with it. I've mostly known people with depression. I've talked to my own mental health professional about it and mentioned I thought bipolar people might be more difficult when they're in a manic phase, at least for me. He nodded in agreement. This person doesn't know their limits as to what they can do, overpromises and doesn't deliver, has bad impulse control in social situations (not violent, just unwise and annoying), and more. This is when I get very irate and do my best to keep it in. They have unsuccessfully tried to pull me in to their sphere (their family is full of enmeshed pulling of others into drama) but I have not allowed that to happen. A discussion of managing experiences with friends who have mental illness could be helpful. I don't know much about bipolar disorder, even after reading about it. How should a person manage their friendship with a person who has it and, if it becomes too much, should I back out of the friendship?
