I Take Depakote For Epilepsy And Last Summer I Started

I take depakote for epilepsy and last summer I started taking propranolol for essential tremors. I've slowly increased the dose and now am taking 50 mg in am and 40 mg. I feel so tired I pull my eyes open in the morning, I'm always tired, no motivation and just feel down in the dumps. Are these mood changes from the propranolol and what else can I take for essential tremors (not gabapentin)?
