Adulting can be tough. Need tips

Hi everyone. I am almost done with my degree and have started to actively look for jobs for the first time in my life .Its tough and confusing . Its also full of possibilities of rejection . Along with this , I am also seeing people celebrating serious and healthy relationships (so happy for them), I see them reaching huge milestones proffessionally and also in their personal lives which seem to be really really far for me right now . I am still not comfortable in doing things independently , maybe because i was never allowed or expected to and now there's just too many tasks , responsibilities and expectations.

This all is scaring me a bit as if I am going to be left behind and my insecurities are making it much tougher for me. I know my life is just starting and stuff but any piece of advice and kind words would help.

Thank you
