If this data is really important, I highly recommend you stop everything now and find a company that specializes in data recovery on SSDs. This will cost money.
The problem as I see it is that because of your lack of knowledge you are much more likely to do something that will make it totally unrecoverable. This chance is increased because I believe that you may be using words incorrectly which would cause people to give you faulty information which further increases your chance of ruining the data.
Hopefully the data wasn't too important and you can take this as a reminder to back up all your data at all times to prevent accidents like this in the future.
I really wish you the best of luck, I just believe that the current situation won't resolve successfully.
