It's not because of the opening at all, it's because your tactics are not good, to put it very mildly. You need to concentrate more on tactics before even thinking about openings. I'm sorry if I seem harsh, but that's the truth.
No, I'm aware my tactics are weak, but I was curious as to why I performed better at one opening vs. another.
I don't know why, but everytime I go for an e4 opening, I end up losing. I've only been getting my wins from Queen's Gambit accepted/declined. For some reason I always end up in a better position that way.
A bunch of my last few losses were e4 openings, if you wanted to take a look.
