When I was young about 12-15 years old I was high school back then.. I usually feel chest pain. It feels like I lost some air, it's hard to breath. It takes about 10-15mins before it become OK again.. I also usually suffered from cannot sleep.. It's like insomia. Years past and I feel the same.. There's a times that it hard to breath and there's a times also that it so hard to sleep. Sometimes I feel also hard to breath when I lay on a bed..
