Depression in relationship??

If you have gone through/is going through depression, how did you managed to balance it with your intimate relationship? Did you end things or cope through it because I currently am just unhappy, and i feel mistrusting forwards my partner, insecure and sensitive to all of his tone or mood change. I’ve no idea if this is heightened from my current mentality, or the relationship is actually feeding it. I don’t want to lost my best friend and I tear up at every thought of it. But I’m not happy right now and esp. being in long distance relationship with him isn’t making me happy either. Tell me which road you guys took and if you managed to find a happy spot in the end. 💜
