I started having problems with my mental health in the first year of uni and had to drop out because of it. I was heaviliy in denial about it and did not receive treatment for a year. Now I'm doing a lot better. I've reapplied to uni, got offers and am determined to beat this thing and get back into education this year.
Bipolar is not a death sentance, with correct treatment, healthy lifestyle and person determination you will beat this. You may not feel it but you are still young, 31 is the new 21 these days. Don't limti yourself. A friend of my mother's who is also bipolar, has a family, 2 kids and a high powered job in the city. A lot of people with this disorder go onto do incredibly well in life, all it takes is determination. Many famous people have bipolar disorder, including Winston Churchill who's determination throughout the world war took down the Nazi war machine. His 'black dog' as he used to call it was also the source of his courage. And although psychiatry in its early stages (he was treated with amphetamines for depression and sleeping pills for mania), he beat all odds through sheer force of will.
