Sounds very similar to the shit ive gone thru.

Get your thyroid levels tested. Can’t remember if its hyperthyroidism or hypothyroidism but one of them has symptoms that are very similar to depression. Low energy, tired, lack of motivation, feeling drained. It took a long time to get myself on the right medication but the biggest break thru in that time was getting my thyroid levels straightened out. Most of that time was spent with professionals who thought I was suffering from depression.

Id recommend seeing someone that specializes in ADHD and all the other comorbidity disorders. As well as asking your primary for a script to test your thyroid levels.
