Should I just give up on Malenia?

I was starting to think I’m genuinely bad at the game. Walked away from Malenia for a bit, ended up smashing through Godfrey and Radagon/EB on my first tries with no spirit ashes. So that felt anti climactic. Ive beaten every other boss. Even with +10 Tiche, I haven’t gotten closer than getting Malenia down to about 30% health in her second phase. Is it just about getting lucky? If I find Malenia punishingly difficult, is Shadow of the Erdtree even worth playing? I’m running a strength/faith build, level 164, 60 vigor, fully upgraded weapon and seal. Haligtree area in general for me was pushing the difficulty level that I still find fun, is SOTE going to just be frustrating?
