Relationships are hard anyway but when you add a mental illness into the mix it can be very hard. For example my boyfriend wants me to express my emotions. Well I have a hard time identifying an emotion let alone express it. Meaning talk about it. In my home life growing up we did not express emotion only happiness. And yes anger too. But that is it.
My therapist gave me a sheet with many different words for describing an emotion. Emojis help too. I use them all the time while texting.
There are resources and support groups you can go to and support one another.
