You aren't the only one who are experiencing what you are feeling right now. One thing more is that you sold your Bitcoins because of a personal problem. Come to think of it. What will happen if you just hold your Bitcoins and didn't focused on your problem.

For sure there are some investors there who sold their holdings at much higher price than where you sold it but still feeling regret because they didn't know that Bitcoin will move like this. Nobody expected this move I think. This move is a combination of the institutions buying Bitcoin and the hype that is being done by those huge media channels.

The only thing that you can do right now is to just wait for a correction and buy again. I know what you are feeling right now but just move on and wait for a time to re-enter to the market.
