Things only great people achieve are challenging.
The frame you put over these moments might help you a lot.
Instead of suffering you can say something was challenging or “full of your character’s growth” - understanding that every second you push through while others stop and give up, is another step towards your greatness.
Ofc it is great to look for paths and tools that will allow you to move forward as easily as you can - work in the smartest ways you can find.
Perceiving the challenging times
as those that are most fruitful
(because literally everyone else around you quits here making you rarer and rarer and ahead of them
AND because these moments are the ones that are building your character into a stronger and more capable one)
You can smile through it - being absolutely grateful to the universe for making you into someone who can surpass others
and for understanding that the challenge and pain are not here to put you down - the universe doesn’t put you through this to bully you - it puts you through this because this IS part of the process to make you into the top world beast that you want to be.
You know if the thing was easy everyone would do it and get there.
And if the hero of the story becomes the most amazing one with no effort of challenge - was it even real in the first place?
This is what makes your victory sweet.
This process is what makes you better and more ready to take on more and more.
The fact that YOU are the one who does it anyway is a blessing because it makes you the rarest, strongest, most determined and most powerful being. Everyone else curls up and cries and copes away.
You can envision yourself being calm and calculated and determined even in the most terrifying times of a normie and know that it was not a one-day change that made you this way - it was small step by step - every single time you pushed through despite not wanting to with a smile on your face. Those are the times that make a warrior. Cherish them. No comfort will ever bring you growth. THIS IS GROWTH.
hamdellah brother life is good 
Also have no clue what subs sorry but I did find that turning it around into something positive - seeing it as a goldmine of amazing results and strength helps me.
Wish you luck!
Also its good to note that not every unpleasant and painful thing you do has no easier solution so if you find ways that work better, take them! If some things just are challenging, harness them - kiss them - thank the universe for them. These tasks are the ones that make you so godlike in the end no matter what they are as long as you show how strong you are within - like a muscle your mind grows with time.
