@Invalidusername you are going through what appears to be the dark night of the soul. You are not the first to go through this nor will you be the last. Here is a quote:
St. Thérèse of the Child Jesus and the Holy Face, OCD, a 19th-century French nun and Doctor of the Church, wrote of her own experience of the dark night. Her dark night derived from doubt of the existence of eternity, to which doubt she nonetheless did not give intellectual or volitional assent, but rather prevailed by a deepening of her Catholic faith. However, she painfully suffered through this prolonged period of spiritual darkness, even declaring to her fellow nuns: "If you only knew what darkness I am plunged into..!"
While this spiritual crisis is usually temporary, it may endure for a long time. The "dark night" of St.
Paul of the Cross in the 18th century endured 45 years, from which he ultimately recovered. The dark night of
St. Teresa of Calcutta, whose own name in religion she selected in honor of St. Thérèse, "may be the most extensive such case on record", having endured from 1948 almost until her death in 1997, with only brief interludes of relief, according to her letters
Even Mother Teresa experienced what you are experiencing, hope is not lost. You may what to do some spiritual reading, take a retreat some monasteries offer such things so you an clear your head. Remember this:
Footprints in the Sand
One night I dreamed I was walking along the beach with the Lord.
Many scenes from my life flashed across the sky.
In each scene I noticed footprints in the sand.
Sometimes there were two sets of footprints,
other times there were one set of footprints.
This bothered me because I noticed
that during the low periods of my life,
when I was suffering from
anguish, sorrow or defeat,
I could see only one set of footprints.
So I said to the Lord,
"You promised me Lord,
that if I followed you,
you would walk with me always.
But I have noticed that during
the most trying periods of my life
there have only been one
set of footprints in the sand.
Why, when I needed you most,
you have not been there for me?"
The Lord replied,
"The times when you have
seen only one set of footprints,
is when I carried you."
