I've experienced a lot in terms of downfalls and drawbacks and am still here, ready and willing to be a shoulder to lean on, an ear to hear your problems or give you congratulations, and a mouth to encourage you to find your own solution to something that is uniquely yours. We can have similar issues, but we all deal with them differently.
Your problems are not invalid and your worth as a person is not a measure of how well you handle them. You are priceless. You are worth the effort. You are loved.
