Both me and my H deal with BP2. We have each made mistakes, esp. when hypo or severely depressed. We hustle most of the time, trying to make up for those mistakes. It does often seem hopeless, esp since we are older now and have less time to make up for said mistakes.
All we can do is to keep trying. I do understand feeling buried by mistakes and feeling hopeless while trying to dig my way out.
You are definitely not alone.
