<human>: Can you summarize the given text in a few sentences?

My boyfriend and I have been together for about three years now. We have been living together for approximately a year. Things started off great, however, he lost his job about a year ago, and things have gone downhill since then. Initially I assumed this was because he was not working and was depressed, but he has recently gone back to work and it doesn't appear to be getting any better. 

He deals with a lot of anxiety and depression, so I have done my best to be supportive through this very difficult transition in his life. However, it is getting to a point where I feel like I can no longer support him to the degree that he needs, I'm losing the ability to continue being his sole source of emotional support day after day, and I feel awful about it. However, I also feel like I'm not getting the support I need at times. Lately I've been feeling like I'm giving a lot of support and not receiving much in return. I feel we have very different perspectives on the world. He tends to catastrophize, so there is something new every day that is completely world ending, and I'm running out of energy to keep up. 

The times when he is not stressed out about something are great, we love spending time together, and I feel like he really gets me. But when he's feeling down it can be really hard and I feel like it's really starting to impact my ability to take care of myself. 

I don't really feel like I'm ready to give up on this relationship yet, but something's gotta give. We can't go on like this forever and I don't know how to break us out of the rut we appear to be stuck in. 

If anyone has any suggestion, it would be greatly appreciated. Thanks!
