Feeling like giving up

I don’t really know where I’m going with this post, but I just need to let it out. I’ve been TTC for almost 4 years after a miscarriage. I’ve been taking supplements, eating healthier, doing everything I can and it just doesn’t seem to be working. It’s getting to the point where all of these efforts are creating arguments between my partner and I, and it’s just making me so stressed and tired. I feel so damaged and untouchable and it’s just taking a toll on me in general. Don’t really know what to do at this point, and I just feel like giving up.
