Not at all Charlie.
I remember feeling exactly like this about a year and a half ago, had a very depressing period and felt like MY life was pointless and I was seriously unhappy with myself.
I snapped out of it but low and behold Ive been down in the dumps at stages again. I think everybody does, its just some people have frequent waves of good times and bad times and have different lengths of it too.
Surround yourself with positive people, laugh more and try to accept yourself and be yourself at all times - dont hold back.
It wont happen over night and youll go back in your shell in some situations, I do, but just remember youre not always gonna feel like you do right now.
I say to myself that Imma try living in the moment more rather than planning into the future.
