Yes mistakes I made hurt people, caused them pain, damaged them all to extents I can never make better, but I do try to make amends by being a nice person now, sticking up for the underdog, fighting people's causes who can't fight their own and in trying to live a good life. You can't go back, but you can learn from your mistakes. We all make them on some scale or another, but the best we can hope for is that we realise them, learn from them and do our best to make sure they never happen again either to us or to anyone we can advise in a similar circumstance. Don't beat yourself up Connemmara, people will have done far worse than you and be living with no consience of it at all in some cases, you have done what you can do and are thinking about it, time now to forgive yourself, move on and enjoy your life.
