Perhaps, tolerance has appeared.
Change the variety. Or pause for a week. Should help. If suddenly "hard" or do not want a week. At least be patient on weekdays, and on weekends, when you are in a good mood, try it.
There may be several reasons:
1) the type / variety of grass has changed. Everyone knows that the magical effect of herb is based on the THC it contains. but everyone forgets that there is also such a thing as cannabidiol (CBD). So he then acts in a nailing way - despondency, the state of a vegetable, etc.
2) tolerance has increased. If you have been using for a long time (at least 3 months) and often (at least once every 1-3 days) it is quite possible that the brain has adapted and is no longer rushing. Try to find something stronger (more THC) or take a break for at least a month
3) you have a weak and unstable psyche, a lot of sad thoughts and fears in your head. Due to changes in the work of neurotransmitters in the brain, all this creeps out - then you'd better quit, out of harm's way
