At least that's what I know from first-hand experience.

Misalignment does.

It's not the amount of hours spent in the grind that gets you down
but it's the distance between this moment and
your desire to be:

-- somewhere else
-- with someone else
-- doing something else.

It's the resistance to what is, and feeling that there is no alternative, that is exhausting.

Feeling trapped is the ugliest sensation.

It brings to:

-- isolation
-- disengagement and
-- disconnection to self and others.

Liberating from that trap is absolutely possible and
it doesn't requires years of practicing anything
but it requires a radically different approach

which is that to find out the source of your suffering
inside of you, not outside.

Sorry but unless you embark in the journey of self inquiry, where you experience freedom that is in you, as you,

there's no positive thinking
no blaming or shaming that will ever free you up
from the trap you are living now.

If you don't know how to start this process try this:

-- open up to another human being (writing may also help but imo the exposure to another person will bring the emotional charge and connection to a completely different, quicker and more impactful level than writing)
-- hear your self talk
-- challenge what you hear
-- see the through the thoughts that you have around the emotion that scares you the most
-- realise that "your" thoughts and "your" attempts to bury that emotion are the same thing.

See that thing,
understand the nature of it
freedom will be observing
as you.

Resisting to what is, through thoughts, for the fear of experiencing pain
is misalignment.

Life is to be lived and pain is inevitable,
suffering for the fear of experiencing the pain
that you are actually already experiencing
isn't necessary.
