Weed has turned on me.

Used to smoke for 8 years straight, Started smoking back weed after almost a year break. I always mix it with grabba been on and off for 2 months. I developed anxiety. I remember going into my first ever full blown panic attack off the weed last month, mind you I have years of experience. Weed turned on me. This new age weed has me going through it 😢. My nose gets stuffed when I smoke and I’m having shortness of breath even when I don’t smoke. My chest hurts sometimes to. I’m quitting today but anyone experienced this? Has it gotten better. 😔
