  Thank you for asking. Here are some treatment modalities you can pick from, Remember parkinsons and RLS excacerbates each other. So be watchful and compliant in your medication with a constant touch to 
neurologist and GP
Here is the treatment option list.
A-Antiparkinson Agents, Dopamine Agonists

  Ropinirole (Requip, Requip XL)
  Levodopa with carbidopa (Sinemet, Parcopa)

G- Herbal Remedy

      Anecdotal evidence from Japan suggests that yokukansan (an   
      herbal remedy) is effective in the treatment of RLS

But you need a close monitoring by your Neurologist for RLS. Mean while see the 
Psychiatrist for Depressive sympoms. Sign up to Group therapies, vocational and recreational therapies. And I am sure you will feel better.
