Mix crushed graham crackers with the butter. Press into bottom of a 10 inch pie pan. Mix water, gelatin, lemon juice and cottage cheese in blender until smooth. In a large bowl, fold sliced strawberries and whipped topping into the cheese mixture. Pour over prepared crust.
Heat cherry juice and cornstarch in a medium pan until thickened. Add the cherries. Remove from heat and cool. Add sweetener. (This will be tart, if you like a sweeter taste, add more sweetener.) Pour over the cheese layer and chill thoroughly. (For a sweeter cherry taste, you may use sweet cherries instead of tart.)
