Just like OP had said, it took OP off balance because from what I understood, not that OP does not have funds but it looks like OP has spent some funds in cash as I may understand may not too long to that event i guess and from what OP had said in previous comment that there are other investment available to get funds from but the time interval it would take will involve process and procedures which does not go well so OP had to resolve by selling the available bitcoin in asset to sort things out and I was made to understand that OP had a pending credit alert which could replace the sold bitcoin.
This should not be a thing of regret as bitcoin is money and can serve any purpose as long as you have it available for use. That was the sole purpose for which Satoshi developed the bitcoin. OP, you should know that so you did a well and have nothing to regret about but it would be good you have replaced it as you have said.
We should think back on the main reason on why we had been saving up? which is that there's something we could use on the time that we are in need or emergency and thats why its not really that something that you should really be stressing up yourself just because you had spend up the coins you've been saving up specially Bitcoin but to think back that it was the main sole purpose on why we have done this.
Not only for emergency why we save money, but also were saving for the things that we want in life like our dream houses or car. From my experience, I invest and save my money in bitcoin from my extra money for a long time of course I know the volatile situation of bitcoin but having a reserved token is my way of savings. Of course my purpose is to save a lot for wanting to have my dream car. But along the way my friend needed some funds for his bills and his son's birthday is coming up so he asked for help for money. Me as a good friend I'd sell my bitcoin since I don't have any cash on hand and transferred some money to his account. You know a lot would feel like they've lost something they own but for me, it really feels good to help I was there in his son birthday and I really enjoyed it he said "thank you man I couldn't do this without your help" I don't ask for return but he really said if I need his help he's one call away. Our relationship as a friend strengthen we were friends like 6 years since high school.
Its not really just that right that you do have those regrets on selling it early because it was really meant for that condition on why you are saving up on the first place.
Exactly, you meant to spend your money because you'll not save until the day you die. You can't bring your assets in the after life so enjoy a little spend some money. Doesn't mean to spend all of it, secure some for the future and the extra money why not treat yourself.
There is nothing wrong in having multiple savings option but atleast one of them should be able to cater for such emergency when the needs arises just like occurrence.
