I'm someone who's full of fear, and while the ones I really have issues with right now are heights, scary bullies and also worried I'll get abandoned, there is another pretty scary one...
...and yeah, same reasons as CrazyBunnyCoaster said, the future. I'm someone who's got autism and special needs, and I'm worried I can't survive on my own due to the fact I'm finding it extremely hard to keep my general health up. I would exercise and do walks, but my brother has been so abusive and stressing me lately that I don't have the time to do it, plus I find so many health foods bland and tasteless in general, particularly vegetables. I also have a family history of diabetes so I also have fear that I'll get it, and trust me diabetic life if you have a fear of needles turns into a complete nightmare.
I'm also worried my anti-social and mental health issues will make it harder for me to live as well, because you all know what bad things are hitting my family right now.
