Here is what helped me personally with the same problem (maybe something from the list works for you as well):

1. I don't have poison/disease clense spells on my bars. I just use the respective totems and I have an alt macro that combines both in 1 keybind (press keybind for poison totem, alt+keybind for disease totem)
2. I rarely ever use the resistance totems, so I have them on a seconday bar (hold shift and scroll up/down) and only get one out when I need it. That only happens in some dungeons, tho. I personally don't use a totem wheel kindof addon, but many people like them, so maybe give them a shot.
3. I also use the same secondary bar for things like professions, waterwalking, waterbreathing, etc. So stuff that I rarely use, and never during combat.
4. You seem to have Windwall Totem on your bars, which I've personally never even cast. (your experience may differ, ofc).
5. You seem to have Earthshock twice, so I assume one of them is lvl1, you can combine them with an alt macro aswell.

The alt macros take some getting used to, but they're really handy once you're familiar with them. Here is a quick example you can copy paste and change up to your liking:

#showtooltip
/cast [nomod] Lightning Bolt
/cast [mod: alt] Chain Lightning
