How to tell your boyfriend or girlfriend you have depression?

Honesty. Being honest is the key to any successful relationship. Long terms it'll benefit you and your bf/gf. Rather overcome it together with support than none.

Sit them down and talk about it openly. Depression is something that should be talked about without is being taboo, they will support you

Your partner will do whatever they can to help and support you. The best way to tell them is to be very honest and open to any questions, and you should reassure them that it is not because of them so they don't feel responsible or guilty.

You can start by telling them about your symptoms and then explain to them about how the illness works.

Just tell them! :) They definitely will understand you if they truly love you for who you are. Otherwise its about time to move on.

This is a really difficult one! It might start in small ways, for example, just by mentioning the word in conversation and see how they react. If you don't feel up to telling them in person, maybe a text or email with a link to a blog post or website that you feel might help them understand?

Telling a significant other can be extremely difficult, but it could very well be extremely beneficial, as you would have a great support system. I recommend sitting down with your boyfriend/girlfriend and explaining exactly what you're feeling. Make sure to have answers to any questions this person may have and even have some resources available for them to do some research. It's also a good idea to have an idea of how you want this person to help you.

Just be yourself. Tell what you feel. But be ready not all people understand what it means. It is better to start to talk about your worries and see the reaction.

Just talk freely about what you have, explain that's more than just a feeling. He/she will try understand that and have support is always helpful to get out of depression.

You can tell if you're boyfriend or girlfriend has depression if her mood suddenly changes, she gets serious all the time and self-harm (if she did)
