Hello, I am a 27 year old male. I've been having anxiety issues since I was about 17 so close to ten years. My first panic attack in my sleep caused it all. I fell a sleep, my mouth got dry because it was winter and for a quick second I stopped breathing, which made my brain go into panic mode which caused me a panic attack in my sleep which caused everything to go down hill for ten years. After that i always felt depressed, scared, trapped. I got on multiple meds took them three years but got sick of them because they were affecting my happiness, made me numb inside. So I quit them, and felt way better w out them. But since i dont take anything for anxiety anymore, i have not had one bad anxiety attack since. I only had 2 big panic attacks in ten years, but everything else is mostly my anxiety. Once i got off the meds i started fearing driving over bridges (somehow this was never the case on meds) and more scared of heights and elevators because i hate the feeling of being trapped. But the last 10 years my biggest worry was outer space. Its so infinite and it makes me feel claustrophobic here on earth. Knowing that there is no way out of outerspace makes me get anxious alot and panicky. This only HAPPENS at night. So my question is what causes this weird thought and fear thats been bothering me? I could care less about outerspace, but thinking of how inifinte is with no escape gives me ALOT OF ANXIETY. Is there an explanation to this?
