The trully disappointing are your parents, for not supporting your life's choices. When we are young, we make mistakes, but that's how we learn, it's not a reason for make you feel like you are a dissappointment.
Live your life, be the best version and love yourself ٩(๑❛ᴗ❛๑)۶
My life has been wonderful, and nothing horrible has occurred to me, but I'm exhausted and unhappy for some reason. I tried looking at things more optimistically, but it didn't work, and I'm back to square one, so I guess I'll have to try again.....as for talent, I don't really think I have one
For that, if I can give you my advice, is that you try something different to change how you feel (new hobbies that you didn't dare to try before, meeting friends to do anything...) but my number one advice is to look for help. A psicologist will help you to find the inner reason for your unhappiness, and work from there to come back to normal.
Those feelings you have are usual to appear in the most unsuspected moments, all of us had gotten them, but not all of us have found the way to get rid of them..
*Gasp* Talent shows.....I loathe it as I don't have any talent to show aside from being a big disappointment
