- Your family doesn't know how much difficulties and pressure you go through in your daily life or in your job. 

- And your work doesn't know the circumstances of your life and your home. 

- Your colleagues, your friends, and loved ones will not understand the size of the new and old responsibilities that are above you. 

- And your partner is always expecting unconditional love and support from you, he/she wont understand the amount of pressure you go through no matter how much you talk and explain to him/her.

No one will understand what you're really going through and they most likely don't appreciate efforts.
