It is completely normal, you have to fight hard to get out of it. It takes a lot of self 'talk' -- control of your thoughts, treating yourself well.
For example, there's a difference in running for enjoyment that feels like self-love and self-care vs a type of 'punishment' or a 'you're not quite there yet' mentality, constant self-correction. Work hard to treat yourself with love and care, think great things about yourself.
