Venting about job

My bf got annoyed at me for venting about my job so much so i’ve been just avoiding talking about it. im actively looking for a new job tho so I am making positive advances in this instead of just crying about it. but I have my weak moments still and today I was really down about the job again. I said that to my bf that i was upset and I could tell he’s annoyed 😭😭 l haven’t talked about it in awhile. I guess I should just avoid venting to him in general. it’s just worrisome bc being in a healthcare related field… it’s really hard on your mental health. I don’t want to drown my partner in my struggles but I also want to make sure they can support me…
