Which Med Should I Try Next?

My main problems:

• Inability to stick to lowly stimulating tasks
• Executive dysfunction
• Forgetting what I was doing every 2 minutes
  Bonus mention: random bouts of anxiety
  (Don't know which subtype this amounts to)

Meds I've tried so far:

1. Atomoxetine (extinguished the anxiety but did nothing for the ADHD)
2. Methylphenidate (amplified the ED, essentially gluing me to even boring tasks. This helped for reading but not for my executively intensive physics homework, where I literally had to use my inner voice to guide myself. Did nothing for the forgetfulness.)

Has anyone had a similar response? What ended up working? I'm in the UK so there's no Aderall.
