is vyvanse for me?

i think i am having some problems with vyvanse. the first 2 months of vyvanse was life changing but i was recently raised to 30mg after 3 months (because it stopped working for me one day). its been 2 weeks and ive almost been feeling worse?

I still feel somewhat focused but my motivation is out the window and am unable to even open my laptop for school.

i have short periods where i feel super talkative and energetic, but after those periods, i feel tired and unable to talk or do anything. around 3 hours after taking the meds, i feel super anxious and nauseous (lasting hours). my doctor told me to get a vitamin/mineral test and all was normal except for iron levels.

i am not sure if i need to wait and see if the side effects go away and motivation comes back or if i need to change dosage/medication.
