I am not a product of my circumstances; I am a product of my decisions.
My own thoughts and actions, while they may have been of good intention, define(d) the outcome(s). My excuses and blaming, while arguably accurate, are not productive or helpful.
Only I can change my behavior. If I embrace blame and despair, then I'm not fixing the problem. Nobody else can fix me, only I can.
I need to stop blaming everyone and everything else for my current miseries, and accept that my life is the product of my actions and decisions. If I'm unhappy, then it's my fault. Not my parents', my spouse, my jobs' fault - They may be a source, but it's my decision to allow their continued existence in my life. Detaching the sources of misery in my life, well, that's on me.
Only I can change it.
And I did. I took control and weeded my personal garden. If I was able to do it, so can you.
