You must remember that it’s okay not to be okay. It’s not your fault that you need help. Everyone needs it sometimes. It’s important that you know where to go if you are struggling with your problems at work, or in your personal life. You can (and should) ask for help doesn’t matter if the issue is related to your mental health, or physical health. Your company’s HR staff, your manager, your supervisor, all these people are there for you. They will try to help you and if they can’t they’ll tell you who can.
Go out there and ask. It’s easier to solve problems together.
