I'm wondering what stronger looks like, in your experience.
I feel pretty naive in regards to a lot of things in life, as though I failed to experience enough (especially romantically) to develop a thick enough skin which I've seen in other people who have been through multiple breaks ups and heartaches. I've dealt with betrayal, employment struggles, financial struggles, huge mistakes, loneliness, etc, but when I look back I feel like these things have only made me more inward, defensive, self-loathing and adept at translating any hardship as evidence of personal failing. I'm tempted at times to think some higher power is determining the success and failure of everyone's lives, and that my own failures and suffering are justified punishment for failing to be a good person. Which isn't to say I deny all personal agency, or acknowledge that countless people suffer through no fault of their own, but only that I find it easy to enter the mindframe of deserving failure.
What I find is that any hardships I've faced as a result of random events or the actions of others have been relatively easy to process, and have allowed me to grow wiser. But what I really struggle to deal with are personal failings, especially those where I have let others down or not treated them as well as I could and should have, or at least when I judge that to be the case.
