I am going to be the cold voice of reason:
The bike may have sentimental value, but in the end it was a factory made, anonymous bike that you just happened to purchase.
Now, if it were a custom made frame that you had gone through hell and high water to meet your needs, I would say it may be worth saving.
Find whatever photos you have of when the bike was young and move on.
If you endeavor, you will find a better bike
