How do you get rid of paralysis analysis and anxiety to start ?

I feel so afraid to restart life all over again, I know we are lucky to wake up everyday to live another day but sighs I'm not even taking that as an advantage. I'm just living in the past and mentally feel tortured. Like why do I keep fighting with myself and what am I even getting out from this. Like this thoughts are driving me so crazy to a point I feel exhausted and defeated. This is also affecting me physically because I don't have willpower to even exercise. Years of procrasnation due to fear and shame has caused my life to be stagnant. Lately I have been pushing myself to go for walks and exercise with resistance bands but next day I end up food binging as if all the control I tried to have is gone.

I've been telling myself I'll apply for jobs in January 2025 but I still have not applied for 1 job. I even told myself I will definitely research and ask people what career path to pursue but I have not done that either. I have lost accountability and self respect. I'm so tired of figuring out what the hell is wrong with me.
