How can I lose my fear of going out on the street?

I have not been out on the streets for years, I am very afraid of not being able to defend myself or be kidnapped and tortured, I know it sounds like paranoia but it is true it is something that happens a lot.
I have not gone out for four years, not even for a day because of the great fear I feel.
I am afraid of what is out there. I tried to overcome my fear with therapy but I could not, I have been treated by three different therapists (the therapies were virtual because I have not been out for four years) and even then it did not help me and I continued with the fear, it is because my fear is not so much Psychological, it is due to a greater extent to my physical state which is very weak, so that causes me a lot of depression.
What if I go out one day and someone kidnaps me to torture me and I can't defend myself or run (I suffer from dysautonomia, it would be difficult for me to run or force myself to avoid being kidnapped)

Do you suggest something to face my fear?

It hurts... 😓 I wish it were so easy, but I don't have anyone, I'm an orphan therefore I don't have a family.
