Bitcoin is still trading at sub-40K levels and you should not waste much time and buy back your coins (probably at a loss). I don't know which coins you were holding, but the alts went down on average by 40%-50% and that means that you will incur a higher loss if you buy them back. Anyway, don't get disheartened. Take this as a lesson. During my initial days (in 2012), I also did several mistakes with my coins. It's all part of life and I hope you will be in profit very soon. BTW, there is no point in regretting about past mistakes.. treat them as valuable lessons.
