I'm a 20 year old guy who went skydiving a year ago, I loved it (tandem) although I think I almost blacked out towards the end of the free fall. As we got higher in altitude, (we jumped at 14,000 ft highest jump our state offered) I got lightheaded and kinda dizzy and when we fell I couldn't breathe, felt like air was being sucked from my lungs and towards the end I felt numb. When the chute deployed it knocked wind outta me but when the instructor loosened the straps I felt better and all in all enjoyed the experience. I am signed up for AFF courses next year now and am curious if, given the lightheadedness and breathing deal, this is unsafe, or if breathing while in free fall normally is a bit more challenging.
Something else to note is I do have anxiety, but it's more centered on medical things, I've never let it stop me doing things I truly enjoy and I do want to get licensed to skydive. So my biggest fear would be losing consciousness in the air, I'm not afraid to do the jumping itself.
Of course it was my first time ever in a plane, or any aircraft, I still have yet to land in one, and I'm curious if, for someone who experienced these problems on my first tandem, it's safe to continue through AFF courses next spring (I'll probably do it anyway)
