Too much change?

As u might get from the headline, things have changed, and Im not sure I feel comfortable with it.
Lots of ppl have left as I described in the last post I made, and even more ppl have left since then; We've lost Artfool, Arcx, Onck, Wisqa and more.. Those ppl were great DPS'ers, great Tanks and Healers, but most of all they were all great players and persons.
Artfool made a post on our guildwebsite to break our situation down for ppl as it was, and as I replied to him, it honestly gave me more energy and hope about rebuilding Orbis Tertius - But Im not too sure if I have that energy anymore.. Too often I've experienced to be stuck in a guild filled with friends who kept me from moving on with my own gaming and "life", too often I've let big chances pass my nose due to fake hope and dreams.. Should I still hope and dream about a new, strong Orbis?
To tell u the truth, I dont know anymore.. On one hand, that would be the right thing to do - to stay and fight for new and better times. On the other hand, I shouldn't hold myself back if I get the chance to move on and become even better.
Maybe I have taken too much on my shoulders? Currently Im top DPS in the guild (when my good friend Denmark doesnt beat me :P) and I might aswell be one of the fastest members to move from eventual damagedealing features within an encounter. I expect of myself, everytime we raid, that I show everything Im capable of - I do not hold back even tho it might sometimes be easier and more relaxing. That might be stupid to some of u, but thats how I am, and thats what earns respect, atleast in my book.
Now, dont misunderstand me, ppl are indeed giving me respect even tho I dont demand them to =) Im just not sure I can keep on giving them the Nash they know.

Im burning out, my hopes cracks more and more as I see my friends leave us, it tears me down..

To be honest with u, I dont know what to do.. I have actually been looking at a few guildwebsites to seek changes and to find happiness again in my endgaming. But Im not one of those ppl who just run off when things gets too hard, never been and never will be - so I am deeply in doubt..

Is it too much change, or can Nash survive the dark time we are currently facing? Only time will show..
