Can I please just say to anyone who may read this thread if you are feeling isolated or down there is always some one to talk to, be it friends, family, colleagues or whomever please do talk about it.
Many rail company's have Employee Assistance Programs these are anonymous and confidential, no information goes back to your employer and they are staffed by professionals who can help.
If your employer doesn't have an EAP then speak to either Mind on 0300 123 3393 or Samaritans on 08457 90 90 90.
I would also say for the commenting further on this thread please be mindful of the follow guidance from the Samaritans
