OCD and Anxiety are destroying my life

I have this mixture of "normal" life stress and exaggerated anxiety. Some things are reasonable things to worry about and others are just nonsense and inbetween the two, so i'm always on a hair trigger.

I can't even handle PMS, a period ends my world. Oh, but don't worry, in 2-3 weeks I'll be having another mental breakdown again, just in time to partially forget the previous one. Does it make it easier knowing it'll calm down for awhile, eventually? No. Every single time is a living nightmare. But when I'm not dealing with that, I still get to enjoy anxiety, depression and OCD anyway. Along with a career that is slowly killing my spirit.

I feel trapped in this existance and everyone is perplexed by my discomfort. I have a husband who doesn't even pretend to understand what I'm going through. He tells me constantly that "no one else cares about" any of the things I obsess or worry over. As though that is supposed to make me feel better. When I tell him it doesn't help, and he's making me feel worse, he will then proceed to grin at me like the cheshire cat, as though that absolves him of any wrong doing, while planting the seeds of anger, guilt and frustration on me. At work, I feel like even though I am very clear with my current concerns of the team, problems, and my current status of burnt out beyond repair, they are not able to help me. If anything, they pile it on. I have problems I feel like I cannot fix, and not just from an anxiety perspective, actual problems. Big problems with no out. I can't take time off because no one has the capacity to fill in for me, and if they HAVE time, they're terrible at their OWN job, and constantly and consistently make extra work for me, making foolish mistakes. They'd just not do the work at all and leave it all for me. You probably think I sound big headed right now, but I'm talking multuple times a day I instruct and remind people to specific requirements, and multiple times a day they let me down. Doing the task wrong, or not at all. Taking the pressure off in any way by instructing the team to do something ends with poor results, if anything, then when you sit them down to explain it, they look at you with vacant bambi eyes "oh? I didn't know." But I'm meant to just take it in stride and relax, right? Watch everyone burn the place to the ground and just grin and bare it. I'd not care, but they impact my work, too, and I'm sick of it. My boss is a gigantic wimp who won't deal with "that confrontational stuff" so I get to have panic attacks all day at my desk while they play dumb and ruin the business.

I struggle with so many basic day to day tasks that other people do without a single second thought. It's not going to improve, it's only going to get worse and worse as I go on longer and longer.

No one cares. And the people who "do" care? I'll never meet. Where do I even go from here.
