Is it normal to ask for help from friends to whom you are not close?

If you don't have other options then it's worth giving it a go. The worst that can happen is that they say no. But also consider looking for professional help if it's getting really bad. Don't know on the nature so I can't comment on it, but there are many charitable organisations that help with most problems

Having some serious trouble. Running out of methods. I don't have many close friends and those who are are not living in the UK. So, I don't know if I should approach those (in the UK) to whom I am not close.
