Last night I smoked marijuana, layed down, then randomly got an erection. Which was weird because I wasn t thinking anything sexual. But went with it and masturbated, about a couple minutes later my heart was beating weird so I stood up and started feeling myself collapse. I woke my brother up and he sat with me to make sure I was okay. While sitting there I could feel my muscles shake, my hands and feet were freezing. Also it felt like I would get really tired then would get a feeling of adrenaline. Today I have felt almost sick like. Feel weak, diharria. Also have been very very hungry all day. So have ate a lot today. Any ideas?
