Free advice, and no, you didn’t ask:
Get your focus off yourself. Get yourself into something of some sort where you give to others. This internally convinces you that you have something to give and thus you have value. There is nothing wrong with being very selfish and doing charity work or tutoring work for the express purpose of getting your focus off your internals. Having your body involved (you go there, you do stuff) is more convincing than mentally and emotionally stewing in your own juices. This is the age in life where things turn up or they turn down. Left alone, they tend to turn down at this age, is what I mean. You have to act.
Make the decision, go, and do. Get your focus off yourself.
I am a born again Christian and an active elder in the Cumberland Presbyterian Church. I am the choir director and the Treasurer of my small church. I am Chairman of the presbyterial Board of Finance and I sit on a denomination level finance committee. I serve on the local non-profit hospice board that raises money for indigent care. I have run the largest hospice fundraiser for the last three years and about to do my fourth.
I greatly value my Christian faith and it has been vital to my not falling apart long before now. But I do not, and never have, believed in Pollyanna Christianity or the Gospel of Prosperity. . . . Christians have great struggles with life also. Just read about the demise of the apostles. My struggles have been hard and spanned many years . . . I am simply tired and frustrated.
