Been stuck in a rut for two years because i overthink

Anyone who can relate? I have literally talked to everybody i am close to, had multiple solutions to try out but each and every time i give it a shot, i come back to the place where i started -- a place of thinking; making lists, planning, trying to make a decision, reflecting on what drives me, who i amm who i want to be and what my purpose in life is. Why do i have to analyze everything when i know that the only solution is to engage, take action. Why do i stand in my own way when i know exactly what i need to do to be happy for the time being? I'm getting sick of myself.
