Vent: Anxiety Since Childhood

So I just really want to talk about this because it's so frustrating, cause I don't understand it. Basically, so there are some nights when my fans' noise makes me think that the security system could be going off even though it's not, and then I imagine worst-case scenarios and plan out what I'd do, and the only way to get it to stop is to turn on my TV or white noise and stuff. Also, when I was a younger I had a big fear that the second I turned 18 I would be homeless unless I could pick a career right that day but never could so it just made me cry and feel super sad and stuff for days sometimes, and I went to a councilor around that time and they even asked me at one point why I kept mentioning being scared of being homeless. And like around that time, I wrote journal entries anytime I felt really bad, and I mentioned homelessness basically every time I mentioned my fear of adulthood in them, along with just being miserable and losing all my interests and personality. Anyway, yeah, I'm not scared of that specifically anymore, but I still hate aging, and talking about career or whatever still makes me the same level of anxious. Also, I don't drive because it scares me too much, but I do have a license. I also can't listen to the news cause it makes me feel super hopeless and stuff so I also don't use most social media anymore and any I do I filter to avoid it cause of how bad it got, so yeah but it's not like i'm thinking about everything that could go wrong with stuff it's specific stuff like i mentioned that makes me anxious, and I think trying to figure out why I feel this way all the time is making me anxious too because I don't know, anyway I just wanted to talk about all of that and like see if anyone related or anything. After all, I don't know exactly why I feel that way and have for so long.
