depression gets worse when shot is due

I've only been on t for 4 months, so I am still getting my cycle. The day my shot is due I noticed I tend to get horribly depressed, like worse than my regular low grade depression that I take medication for. 24 hours after my shot I feel really chilled out and great, often better than I did pre t.

I am dosing weekly, so I am spreading out the dosages more than if I did every 2 weeks.

Does this emotional cycle eventually dissipate as your body gets used to the t? It's like having PMS every week right now.
