Beating myself up over lost gains

I was holding 43,100 shares of ORKT at 1.32$ avg, i sold my shares yesterday at the same price as i thought it was gonna drop more but it stabilized a bit lower. Today the stock went up as much as 40percent and it's killing me. Fucking sucks, it ruined my day :'( my 56K$ could have been 78.4K$ if i had just held 24h longer, fuck my life
