Hang in there ((((((((Radioflyer))))))

No memories don't get erased forever. barring a phsical health probelm that results in brain cell loss memories are stored forever.

It might just be that your brain knows you are not ready yet to know what all your memories are yet. Hang in there and take it one step at a time. Sometimes getting there slower is better then getting there faster and creating more problems in the process.
