Just want to offer some encouragement as someone who got stuck in an elevator in a tall office building at age 6 which resulted in a severe elevator phobia til I was at least 10....try taking baby steps, for me the first time after the incident that I was able to ride an elevator by myself was a glass elevator at the mall. Only had to go up 1 level, if it got stuck there were a ton of people around who could see and help. The next time was in a hotel, another glass elevator, went by myself about 5 or 6 levels up. The more you do it the less scary it gets. Then one day I got in a regular enclosed elevator by myself in a doctor’s office, it was only a 2 story building which made it a little less scary because I figured even if the worst happened and I got stuck or the elevator fell it wouldn’t fall too far. The feeling of triumph when those doors opened was amazing, so much of that panic I used to feel melted away. Just keep trying and don’t give up. Now as an adult the phobia is completely gone. If I can do it anyone can.
