I hope it's okay to be realistic here so...yes, no matter how bad things are, unfortunately it can always get worse. Now for the good news...it has a tendency to get better...usually a lot better
People... "normal people" that is, sometimes talk about getting through a hard day. Unfortunately I'm not a "normal people." There have been times when I (and others here I think) have had to struggle through the hour, or the minute, or even the crucial second. Look around and find something good. It may be inside of you.
You've made it this far. Never give up.
