Sharpened Thorns
I got to 80 on a Sylvari, but I don’t think I took that quest…
If you’re an EU player, hit me up. I’m willing to help.

I play sylvari myself, but do not found it too rough. Difficult, but possible for “Loved and Lost” quest without help (and if you bring some friends, your enemy becomes stronger). Through, I chose Priory way to defeat undead in second situation, maybe “Bramble Walls” quest is simplier than “Sharpened Thorns”.
Bramble walls is easier, but also a lot more boring. But both are very doable and never had any issue with either of them. In my opinion only two silvari story lines are broken:
source of the issue and Dead of Winter.
I think your issue is mostly with your class and how good you know how to play it. Leveling a mesmer requires a lot more effort and dodge-skills then a full level 80 mesmer.
Arise, opressed of Tyria!
