SeeSmith on another post here on SP said it well: “You are the LEAST qualified person to judge yourself [when you are in an ill state of mind]”.
Don’t make the mistake of thinking for others, don’t assume you’re a burden or that others are just too “busy with their own lives” to care for you, to help you.
Ask for help. It’s OK to not be OK! Life is not just about its sweet moments.
