One of my doctors once told me there is no magic pill, and I know this is true. For instance, if I take something to help with depression, doesn't it stand to reason this will cause me to feel some hyper or anxious? Or if I take something for anxiety that I will begin to feel lethargic? I also know obsessing over past mistakes only causes us pain and doesn't fix a thing. If it is reasonable, ask the person in the past to forgive you, then move forward. Try to learn from the mistake. None of us are perfect. Wish there were do-overs, but there aren't.
