I been a smoker, Something dramatic happened, I didn't know who am I

I been a smoker for the last 2 yrs. Something dramatic happened, and it made me open my eyes. After quitting cold turkey a few weeks ago. I realize that I didn't no who I'am anymore. I barely sleep, lose my appetite, losing weight, snap at alot when before it was never an issue. To me it's honestly scary because this is not me! My attitude has its ups and down, depression settles in, it's effecting my job, & my relationship with my family. I get night sweats and had a vivid dreams. I'm really trying, it's not easy!!! I just want this to go away!! Please don't judge me! I want to be normal again!!
