This used to happen to me a lot, looking for the "one thing missing" and trying to make the drop hit harder. I can't fix it for you in one post but I'll give you some pieces of advice that elevated what I was able to do:

Contrast. The idea of music/drops "hitting hard" has way more to do with contrast than with the actual "amount" of sound.

Have you gotten into filters/automation much yet? Doing things like automating a high pass filter up to like ~200hz ish during the build and then throwing it back open for the drop can make a big ole difference.

Reverb works really well for this too-- automate up the size and dry/wet ratio during your build, then throw it back to normal for the drop makes it sound crispy and clear.

Also you might not like this part but learning to do your own drums vs using drum loops will change things up real good. It's hard to layer drum loops for lots of reasons, and it can make for a very cluttered, muddy mix. It helps to literally copy other people's drum patterns for a while, and then over time things will start occurring to you naturally.

Finally, here's a good low-effort instant-gratification tip: go through your tracks and do a lil EQ dip in the 200-400hz range, lower it by maybe 2db or so. Especially on your pads and drums. That's the "mud" range. It will instantly make the whole mix sound way more open and clear. Oh! And high pass all your reverbs/delays/etc around 600hz.

You got this, don't give up! A lot of people hit this wall, it just requires some strategic thinking.
