It depends upon the cause, but perhaps try:
Jing Restoration, Hyper State Sleep, Photosynthesis (Patreon, The Sapien Trust) and Pranayama Training for feeling tired all the time.
The Men’s Motivation Stack or Women’s Motivation Stack for no motivation. A few of the audios are: Stop Procrastinating and Overcome Any Addiction: Dopamine Receptor Repair and Dopamine Redux (Google Play, Spotify) or Dopamine Overload.
Depression/Stress/Anxiety Relief, CBD, Oxytocin (Patreon, The Sapien Trust), Acetylcholine (Patreon, The Sapien Trust) and Vagus Nerve Stimulation and the audios in the Anti-Anxiety Stack for anxiety.
Down Syndrome and Cognitive Abnormalities can help with many brain related things and may help with anxiety and motivation also, perhaps even help with feeling tired all the time along with the neurotransmitter audios as that can be related to neurotransmitters and brain function.
