wtf is wrong with me

please respond to this and let me know if you have heard of this happening to other people and/or have experienced it yourself, because i want to know if this is normal.

(sorry for the long post in advance)

so basically sometimes i have these thoughts and i don’t know if they are considered “suicidal thoughts” but sometimes i have these daydream things where i imagine myself jumping off that ledge. i’ll be sitting there thinking, it’s dark, and i’m just sitting there staring at the lights, i cry for a little bit, take my last breath, and jump. that’s it. it just keeps repeating in my head over and over again and it’s very specific. while i imagine those things i have that certain feeling in my stomach, you know, that feeling you have when something really bad just happened and you couldn’t do anything to stop it. in my dreams sometimes as well, i can see the specific bridge i want to jump off of. all of this is really bothering me and whenever i tell someone about it they say they have never heard of that before and they don’t know how to answer if it’s normal or not.

please help
