Get stoned (optional). Getting high is pretty nice.
Note that all human perception is subjective. We can't not be biased. Reality is nihilistic and meaningless, and what meaning we have only exists in the mind.
Whether you choose to have any sense of meaning or not is your call. Focus more on making sure your short meaningless life doesn't go to waste with what little time you and everyone else actually have. That includes not wasting your time on your current insecurities + unhealthy/low self esteem. Try to balance it out. Self worth or not, live your best life just because you can.
