Feeling Lost

Hello all. I have never done anything like this before in my life... but I think now is the time. Im empty and lost inside. I fell nothing anymore, one a happy go getting teenager I am now a 24 year old empty shell. I cant even explain how and why I feel like this. Ever since finishing university I am stuck in a dead end job doing something I never even studied for. It just seems like failure after failure with me. Dissapointing everyone, especially myself. I joined this site just to seek advice or guidance just to point me in the right direction. I miss the old me. Now my lack of energy and willingness is starting to get the better of me and every day just seems like a chore. The repeatition is just so tiring, Im mentally and physically broken.
