It is a fact of life that we all struggle at times. For some of us those struggles can be pretty intense due to mental issues such as clinical depression brought on for many different reasons. No matter what your struggles are we can always choose to fight. The semi colon has become a symbol for "there is more to come." I say find your courage; keep your story alive! It is after all, your story and you're the author of it. What thing I know for sure is that it can and will get better. Never stop your story before the best parts come.
This sticker is a reminder for all of us to keep fighting because there are so many great things to come even if right then we have a hard time seeing it.
