[Native spirit]

Lossing a parent at any age is not easy,and we all look for conformation from different sources to be told that they are ok, your dad id fine and im sure in due time you will hear from him, there is no concept of time in spirit so what may seem a long time to you, may only be seconds to them,
have you looked for the signals from spirit letting you know your dad is around you.
like lights flickering phone ringing and no one there feathers etc.
these happen a lot but ppl tend to dismiss them.

Namaste
