Stress and anxiety

Is there a substitute? Anything to help? Anything i can take to make me not sorry worried , I’m becoming desperate. I started smoking week it’s been going on two months. I try taking NyQuil, nothing is good enough. I’m always down . Anything Dr. prescribed i can consider going to talk to someone about . I need to get my emotions under control, it’s been 3 years it’s only gotten worse over time . I feel myself fighting it but it’s hard . I feel like nobody don’t care about me . I don’t even know if i want sympathy, i just want to disappear go somewhere alone and peaceful. Fall into a deep sleep and be there for weeks , I’m very unhappy . My life is all over the place ,expressing it doesn’t help
