All bottled up in a jar

My heart is all bottled up in a jar

My feelings towards other people and myself is all mixed up
I dont know why, but i cant find happiness in life
Being with friends , hanging out with relatives it's just a temporary enjoyment
But true feelings of happiness in myself ... I just cant find it anymore...

I feel like im wearing a mask
In front of many other people like my friends or relatives
I am naturally fun, happy and quite.. not very but quite positive
But when im alone , Im negative and lonely and sad most of the time

Is there something wrong with me? o.o
Or is it because of someone else?

... To love other people...
... You must love yourself first...
