[SamSik1]

Hi guys, my name is Sammy from the UK. My dad passed away last month and ever since I have experienced so many health issues. Nothing I have ever felt before but as what I have read from the thread, i think I am suffering the same. I had my first panic attack on a plane last month and it's been down hill ever since. When falling asleep it's like someone grabbing me or something scaring me whilst asleep, like u guys have mentioned it's hard to explain.

Need help guys. Any suggestions. Thanks.
