For people who have had this for decades, can you give us tips to cope?

Hello everyone, I don't see many posts in the section of managing DPD. It seems that huge number of people who are on this website have been dealing with this disorder for many years. What did you do to cope? How did you make it so far? and sorry for being rude but what abstained you from committing suicide? Because although I am still in my first year with this disorder, I am already feeling very down and life doesn't seem as bright and promising as it used to look for me before.
