It's more in how we deal with the bad stuff than the events themselves. It's unrealistic to live a fairy tale kind of existence - life is very tough but a lot also depends on perspective. The problem with BPD is that there's a lot of introspection, comparisons, catastrophizing - basically it's difficult to accept our own part in things as well.

You don't have to belong to anyone other than yourself - the point of life is the point you give it. Continue working on the difficulties, accept your limitations and strive for as much as you can. It's all anyone can ask themselves. Feel better soon.
