Do not regret it.
You can feel unworthy of it.
You can feel mad at it.
But do not regret what has been done in the past.
Regret, won't do any good to yourself.
Just look at it, stare at it, think of it, let those damn reflections spontaneously happen within your mind.
Do not resist it.
It'll all be fine.
Make your past become your wisdom. Stop suffering from what happened and what will happen. Your imagination is more capable than that. Keep this in mind.
Move forward to your goals. Gather information to build your world.
You shall find love and peace in the end.
