Excel is getting slower as I add more sheets

[Aphten]

I have a work sheet that utilizes worksheet_change with the code that I have included below. Don't mind all the notes. I am new to VBA. It is a lot, but I am hoping that including all of it will show the entire picture. There is no conditional formatting but I do have some macros assigned to a couple buttons for this sheet.

Private Sub Worksheet_Change(ByVal Target As Range)

    Application.ScreenUpdating = False
    Application.EnableEvents = False

    Dim Changed As Range, c As Range
    Dim CellValue As Variant

I currently have this saved as a macro-enabled template. The original ideas was to use this as a form. I would have one master form that is blank and could just copy the sheet each time I needed to complete a new form. Theoretically I would like to be able to just have this saved as a macro-enabled workbook, but I was worried about messing with the VBA coding for tweaks and messing the whole thing up, so I have it saved as a template as kind of a can't-mess-this-one-up back-up.

The problem I am having, is that once I have more than one copy of this sheet, Excel starts getting extremely slow. It seems to be worse the more copies there are. When there is just one sheet, everything works beautifully. I have been completing the template form and then moving it to another book where all my completed forms are. This new book is still slow, but since the forms are already completed for the most part, and
may only need a little editing, it is not as bad as trying to complete the form when Excel is super slow.

Any suggestions?

Hello @Aphten. I think that it is unlikely that anyone will be able to help you without seeing the files themselves (at least examples). There is a lot of code, that's true. But without example files.
Note: my post does not mean that I undertake to help you so that later there will be no claims against me (there have been cases already). Good luck.
