Yes, I do have three close friends who are bipolar...for me it has not been difficult at all, maybe because they are my age and they have gained such insight over the years.
Our friendship just seems to benefit from all the life lessons they have incorporated, they see life more deeply, and so I especially treasure them in my heart.
First of all, bipolar people are not "wackjobs" like the jerk on the previous post said! I have someone very VERY close to me who is bipolar and I am realizing since his diagnosis that there are many MANY people close to me who are bipolar and I would have never guessed! Mental illness gets such a bad name because of stupid idiots like the post above! Having a loved one diagnosed with bipolar is difficult because you need to stay in close contact with the doctor till they find the right "cocktail" of medication for that individual! So how you "deal" with it?..... Just like you would any other person who is ill. You love them through it! I mean how would you treat a loved one going through chemo treatments? Would you treat them differently because they are sick and seeking treatment? NO I should hope not. Your bipolar friend needs your love, support and to know that you are a STABLE person/thing in there very unstable roller coaster of a life. Put yourself in THEIR shoes and walk just a mile. I guarantee you will see them as more then a "wackjob" like the previous jerk had the balls to answer!
