Hi,
I can only imagine how unsatisfying life maybe feeling when you are feeling discontent with most things. However music seems be your respite from all these feelings. Do hold on to it for now.
Next Steps
The feeling of discontentment, shyness to take on things may be making you feel challenged to pursue things further, this may actually be causing stress to some extent, the very thought that I am discontent with most things may also be adding stress to you subconsciously.
Health Tips
In these circumstances seeking therapy to figure out the core reasons that are causing these feelings and stress may help you work towards overcoming them. You can connect with me if and when you feel comfortable doing so. Take care...
