How to get help.

How do I reach out for help. I’m not sure how to ask anyone close to me for help. I feel like I’d burden them. I’m sad. And they don’t know me that way I’m the happy friend. Idk what to do. Also any remedies for puffy eyes?? Crying before bed gives me puffy eyes really bad and my coworkers always ask about them, I just tell them I’m tired and didn’t sleep much but I don’t think they believe me. Thank you in advance.
