You pretty much know what I would say so I won't say it
Can you at least give yourself credit for your accomplishments and the hurdles you've overcome? We should all aspire to be the best we can. To expend energy aspiring to the talents/accomplishments of someone else is pretty much a waste. Have you looked inward to see where this impossibly high standard is coming from? Do you need the accolades?
We all have to find a way to be content with our own capabilities and talents. You can't enjoy life any other way.
