No regrets: Better said than done

I have been in an emotional funk for the past few months. I often feel depressed, defeated, numb. I know and count my blessings every day: a healthy, beautiful child; a good husband; an education from an impressive university; my health; a family who cares for and supports me. But I find myself walking around in a fog, thinking of all the "what ifs" and "if onlys." I watch acquaintances and friends from my past moving forward in their lives - achieving one success after another - and I feel left behind...so way behind. I know that life is not a race and I shouldn't measure the value of my accomplishments against the accomplishments of others. But I cannot help but feel like my life isn't going as I had planned or wished it would. I feel as though I have chosen the wrong paths that have led me to a dead-end. I find myself struggling to live each day - one day at a time - and to accept that what's done is done. I am finding it difficult to even look for a way out of my situation because I am so fixed on what was and what I wish it could be, instead of focusing on what is. How do I let go off my regrets when I am reminded every day of the discrepancy between what I want and what I have? How can I stop feeling the ugly emotion of envy for what others have and be grateful for what is in front of me, wihout losing the ambition to work towards more for myself and my family?

A decade ago, my personal motto was "No regrets." Today, sadly, I have many.
