Hey, you might have seen me post this info on other threads but just in case you didn't & just in case it could be helpful to you at all....
I went to Beachyhead a couple of years ago with the intention of jumping. I chickened out but I did some research first, some of which you might be interested in.
1. There is a lot of YT videos which might help avoid Samaritans/pro-lifers/other interfering individuals & shows what it looks like up there (but good to go & check it out in person first if possible) & there's other useful info in them as well.
2. I caught the train to Eastbourne & walked up, mainly to avoid detection.
People who use a taxi to go up there & appear distressed or in any way suspicious (even being alone can appear suspicious) get caught out because the drivers have a special code they can use to alert the dispatch person in their office who then calls the police to come & stop you.
3. Going to the pub alone, especially if you appear distressed/anxious/suspicious often results in the staff calling the police (&/or Samaritans/other).
But if you chicken out & need a taxi back to the station they're helpful enough call one for you.
4. There used to be flowers & crosses where people had successfully jumped from, they are no longer there.
Jumping from the wrong place can lead to failure (& usually bad injuries & a rescue mission which puts others in danger) because you can land on outcrops of rock. Most of beachyhead & nearby is not a sheer drop even though it looks like it in most places.
