How to deal with self doubt ?

24M here Not achieved much until now. I do have a job But I Don’t have a well defined career path and basically totally lost in what to do in life . Being the eldest kid in family and everyday it feels like time is running out and eventually I have to support my family or yk settle down I don’t compare myself so it’s not about feeling inferior or being jealous I am at the point where I have no faith in me anymore . Lately feeling that I don’t deserve it lmao How do you guys deal with it ? Posting again Bcz last post got removed
