Last night at about half 11. I got a weird message from one of my friends saying "Thanks a lot. Goodbye". It's the goodbye part that has me freaking out. He suffers from anxiety, depression and probably other stuff he hasn't told me. We hang out a lot and he was trying to get through to me earlier that day, asked if he could hang out later and tried to ring me, but I missed the call and didn't ring back as I didn't have the credit. To be honest I don't even know what tone I should read the message in, so I instantly tried to ring him with the very little credit I had. At this point all bad thing were running through my head. Made worse as he didn't pick up his phone. Sent a text and tried to ring him twice. So noticing his best friend was online on facebook I sent him a message telling him that I was worried and he tried to ring him but he got nothing, he even sent him a message. Then we noticed his facebook account had suddenly been deleted. So his best friend contacted his girlfriend to ask her to try get through to him, but there was no answer for her either.
This made me panic more. I suffer from anxiety too and have made myself sick with worry, literally sick. Also I suffered from depression years ago and I know the things that go through your mind. I was meant to be helping him, be the person he can vent to as he felt no one else but me understood what he was going through and I feel like I've let him down. I don't know what to do as I can't contact him and don't know where he is. Right now every alarm bell is ringing in my head, but I don't know if my own anxiety is making me think these things or if there is a ground to be so worried.
