Many people feel they are not worthy, due to many reasons. Some physical e.g. Hormonal, chronic illness or environmental, current or stemming back to childhood and probably a mix of everything. Recognising you need support is the start, but the support needs to be with someone you feel comfortable with, trust and respect.
I had those feelings of worthlessness, but came to the point of being ready for support, which I found with a counsellor and a life coach. The life coaching was done via the telephone. The first thing this wonderful man said was that my worth and value in this world is a given. The effect of this statement has had a profound effect on me and enabled me to start the road to recovery. There were many things I learnt, including what self care is. The counsellor approached things from a different angle, helping understand the past and move on.
I say to you what helped me. " Your worth and value in this world is a given."
If you want to know more of the help I received, books I found helpful etc, then you are welcome to PM me.
