It's not possible to be friends with an angel in the literal sense, as angels are spiritual beings and not physical beings like humans. However, some people believe that angels can communicate with humans and provide guidance and support in times of need.

In this sense, one can have a close relationship with an angel through prayer, meditation, and other spiritual practices. Some people also believe that angels can send signs and messages to them in the form of coincidences or synchronicities, which can help them feel connected to their angelic guide.

Ultimately, whether or not you believe in angels, having a sense of spiritual connection and guidance can be a source of comfort and strength in difficult times.
