How do you stop feeling embarrassed and ashamed of "trying" ?

Yes I admit the reason I'm behind in life is not because of failures but it's more about giving shit about how others might view me so this created lot of insecurities shame and embarrassment top of that social anxiety and fear. Like I know that life is all about trying. If you don't try and don't take actions nothing good will come. But I'm here destroying my future living in embarrassment. No wonder why I don't apply for jobs or don't learn a new skill. Because I just never think highly of myself. I always have self doubts
