I'm a guitarist, guitar is my life but I'm on a bit of a downer?

Ibanez, jackson, esp or even a custom les paul like slash's guitar all have thin necks and trust me, are far easier. I took upon alternate picking about 6 months ago. I can do it much quicker but it may be hard to incorparate it at first becuase if you can do it faster just down picking it like me, i get carried away down picking and forget to alternate pick. I can do hand of blood down picked at full speed down picked but not alternatley, not that fast but it does ache :L. Its messed up tbh just try and keep practicing.
