My own thoughts make me feel overwhelmed and guilty

I feel so overwhelmed right now like I'm constantly runing my own life on purpose because I don't know what else to do to improve my situation. Literally spending hours and hours on the phone being on discord and TikTok. And I keep worrying about my life and situation. I'm even procrastinating on my daily tasks and in guilt I tell myself okay I will do it tomorrow. But this tomorrow has been turned into 3 years now. Like what is wrong with me. Why do I continuously ruin my own life and putting myself down for. I know deep down I need to get a job but I tell myself you have no chance to land a decent job because everybody also is suffering to land a decent job. I want to learn driving but scary thoughts bring me down. I want to go college but my mind says it's too late buddy. Your not even smart first of all. Sighs is like my own thoughts beat me down. I'm not being accountable and lost self control
