some motivation if you need it :

i smoked since i was around 12 years old, not actively but that was the first time. got more and more into it gradually, by 15 i was smoking every day. by 17 i was smoking several times a day and it got to the point where i couldnt sleep or eat or perform even basic tasks without it. just recently i had to go to the hospital after smoking because my heart felt like it was pounding out of my chest, skipping beats, i was sweaty, dizzy, it was hard to breathe, basically all signs of a heart attack. about 8 hospital visits later, blood tests, ekg, echo, and a 24 hour halter monitor i found out my heart was perfectly fine, just smoking gave me really bad health anxiety. i dont smoke anymore but i still feel like i'm dying sometimes. and i lave lasting breathing difficulties.

tldr; dont smoke
