Security cannot be perfect and it's unfortunately that there's often an expectation for it to be. Even if perfect security cannot be achieved, there is value in creating obstacles. Sometimes the obstacles might not be enough and an attack ends up inflicting damage. Sometimes they'll reduce the damage, sometimes they'll give you time to erect better protections or move the protected assets. Have realistic expectations for what is possible and expect that sometimes others will not recognize this value. You are not an island. You cannot make perfect walls on your own. Others will sometimes falter. You will sometimes falter. Some attacks will be successful. Sometimes you will get undeserved blame. Understand the reality of all of this and decide if you can handle that or not. You can't change the behavior of the entire world but you can help keep at least one corner of it safer than it would be without your efforts. Much of this might sound like platitudes but for your mental health, realize that even if you're only having a small positive impact, it's still just that, a positive impact. If that's not enough, then perhaps there are other areas that are better suited to your gifts and needs.
