I don't know what's with me

I know it's a lot, so here's a TL;DR: Work has been rough — my boss keeps criticizing and pressuring me, making me feel useless and drained of motivation. At home, things are strained too; my wife and I love each other but we’ve been struggling with stress, anxiety, and lack of time together. I tend to overthink and make things worse without meaning to. Right now, I just feel stuck, overwhelmed, and in need of some encouragement. --- I've been having some miserable days lately. My boss says I am too slow at work and that I don't understand what he says, and he's been kinda torturing me at work because he wants me to work faster and do things better and I'm trying, I really am, but I feel like I can't. Everyday has been like this. He has been asking me to do stuff and when I show him the work he doesn't like it and makes me see how I've not been doing well and being disappointed with me, because even tho I think they'll not fire me, they keep pressuring me and it's been hell going to work everyday, thinking of what he'll say or how I will be able to survive the day. Somedays are better and there are some parts of my work that I like, but I've been honestly losing my love for this job (graphic design) because of all this, and I'm only not leaving this job because I feel like I need it right, as I'm young and recently married, and a job in this area was hard to find. To add on top of that, my relationship has been hard too. Me and wife have been married for 3 months now. We love each other, we really do, and we have always been best friends. Lately free time has been scarce and we have not been able to have as much time together as we feel we need to bond and to be happier together like we used to. I think it's that, plus my problems at work, plus some other problems with her anxiety and her personal happiness right now, and we have been very unstable. Sometimes I can be pushy in a sense that I can't stop yapping about stuff, especially if I'm nervous or worried about us, and so even with small things I might think there is a problem with her or I did something wrong and I start apologizing and she even explains that it's okay but as I'm worried and anxious that we might have something wrong I don't stop right away, so I spiral a bit and because she gets nervous easily and needs peace to get better we kinda just derail and can't stop each other from getting worse until we both feel very bad. I feel like all this is a cycle that worsens things each day, and everyday I just feel like I'm a failure, I keep messing up: at work, in marriage, and life in general. I can't get better at work, at home I am the one that starts problems accidentally and ruin a good time with my wife, etc. I haven't used this app for a while as I've been testing different ways to organize myself to see what works, but I just needed to ramble about my current situation because I feel overwhelmed and don't know what to do. Hope someone has the time and courage to read all this text, and maybe just gives me some perspective or advice about this, or just says something nice. Thank you everyone ❤️
