I can't tell you what you should do, because that depends on so many details that only you are aware of. I will tell you what I would like to hear from one of my employees if they were in a situation similar to yours. I would like the employee to let me know they have something important to talk about. If remote, I would prefer this conversation to happen either by video teleconference, or by phone. I would not want this conversation via Slack, email, or other written medium, as text is not expressive enough. I would like to hear it explained more or less the way you explained it here. In your post, you describe the condition, how it affects you personally and professionally, the dilemma you find yourself in, and you express concern about the company. Any normal manager would respond with compassion and tell you to take some time off and go see a specialist. It is always difficult for a manager when someone on their team takes unexpected time off. This is especially so in crunch-time situations. However, it is literally their job to manage such situations, even in difficult circumstances. Employees getting sick or requiring time off due to a medical situation is a normal situation, and there are various medical conditions that warrant time off and care. Whether it is a broken wrist, birth of a child, or a mental condition, they should be treated seriously and with compassion.
