I've given up on trying to get a diagnosis for whatever is wrong with me. I'm 28 and tried my best to help myself learn to cope and become a functional and successful member of society. Therapy has never helped as talking doesn't fix any symptoms and there is nothing that has happened to make me the way I am, it's just how i am. I am pretty sure underlying untreated ADHD is behind a lot of my struggles as my father is diagnosed with it and I have alot of problems with concentrating, becoming anxiously bored really easily and impulsivity, but getting an adult diagnosis is near impossible with hardly any money to spend and living in a small city with one psychiatrist to service 32,000 people (how ridiculous is that in this day and age). GPs just hand out SSRIs as a blanket medication without investigating the real issues.

I spent most of the last 10 years on SSRIs and while they help me barely keep it together, they always stop working eventually followed by a period of coming off them which leaves me psychotic and dangerous. 
Sometimes I dream of a future with some kind of mental health test that just tells you exactly what is wrong and what medication will help it, like a physical illness.
