I sometimes get the feeling my writing is fuelled by negative thoughts and over-thinking…but I am a positive over-thinker BTW

Satisfaction

Why am I not satisfied with all the things I’ve got
Are the things I’m yet to get, then would be the lot?
But what if I get it all, all the things I’m yet to get,
My life still feels so empty and so full of regret
Can I change the past, or somehow make amends
Maybe there’s a guidebook that you could recommend
A catalogue of life’s pure gifts, to fill this empty room,
That jealousy and envy, seem keen to just consume
I’m happy for all others, who’ve made their dreams come true,
But what becomes of me when I’m not sure what to do
They all appear to have it, figured out so perfectly
Am I the only person, to feel this melancholy?
