Don't keep beating yourself up for how you've reacted. I would bet that most of us acted in similar ways. Decide that that is the past and you are going from here.
Keep thinking respond instead of react. Give yourself time to think about things before you respond and it will keep you from making a knee-jerk reaction.
That pride, strength and patience that it takes to get through this is already there inside you. You may have to dig for it and sometimes deeper than others, but it's there.
