Ok lemme tell you something, You are not a mistake no one is made for nothing
you are not a disappointment, the problem is that you keep thinking about what you still have to do but not what you have already accomplished, you probably did so many awesome things
even if you have no friends you seem like a person that can easily make friends
your not giving yourself enough credit, you do lots of awesome things and your one of the best memers i know when i was upvoting your memes i was laughing so hard because you memes are so good
and even if some family members have sadly passed on, thats not a reason for you too also, don't die in a stupid way like that
