There are a wide range of mental illnesses that people tend to suffer from, and not all of them will manifest in a typical way. You have probably already heard of things like depression and anxiety, but it is a lot less likely that you will be familiar with the more details kinds of mental illnesses that are common all throughout the world. For example, while you may know what anxiety is, do you have any idea what it entails in a social context? Social anxiety is a unique pathology that often makes it impossible for the people that suffer from it to maintain long term social relationships, and this can dramatically reduce their quality of life once all has been said and is now out of the way.
The reason behind this is that we all need to socialize every once in a while, so if you are a socially anxious person suffice it to say that you are at a real disadvantage. If what we have just described is an accurate representation of what you tend to go through, why not get some Metal Kards printed? They can help break the ice faster than might have been the case otherwise, and you can hand them out to people that you meet so that they can learn about you at a glance without you being forced to form sentences as well as words.
You will obviously need to attend therapy and potentially even take medication as well, but these business cards can help alleviate some of your anxious symptoms by making it a whole lot easier to interact with others. Try it for yourself to see if it works.
