Lingering feeling of apathy and lethargy

I seem to have lost the capacity to feel emotions and I am beginning to feel depersonalised from reality, like I can no longer tell the difference between dreams and real life. I'm not particularly stressed or unhappy but I am feeling tired and unwell for no reason at all. I started crying for no reason last night. I've been depressed before, but this feels different. I thought feeling numb is better than feeling too much emotion, but being fully devoid of emotion is unsettling.

If there's anything I feel, it's that life requires too much effort and I can't be bothered with it. I'm not suicidal, but if I were to slip off in my sleep, I wouldn't be afraid. The logical side of me tell me to snap out of it as life has so much to offer me, but I am not interested and feel no drive to strive for anythingl

I don't know what's wrong with me, the symptoms just suddenly appeared right after I tried weed for the first time, but that was 48 hours ago so the effect should have long been gone. However, I have been feeling that everything in life is pointless on-and-off for the past 12 years or so, even during happy periods of my life, and have lingering lethargy rendering me feeling too tired to do anything besides the necessary.

Could this be comorbid depression with sudden onset of depersonalisation disorder? What can I do about it?

Dear Heartweaver:

My dissociation of five decades is only lately dissipating following five years of therapy/ ongoing healing work that started with my first psychotherapy with a competent, caring and hard working therapist. It tired me a whole lot, to be dissociated, brain fog, exhaustion... living in a dream like state, not here, not there, outside what was happening. It happened to me as a result of being scared to death as a child, again and again and with no one to comfort me. The roll of mental un wellness started its roll down the hill, gathering more and more symptoms and diagnoses ... but it all started with too much fear that overwhelmed me and i split.
