Nothing like ordinary

Feeling so stressed nowadays, and felt like I've got nobody to turn to, so Im sitting here filling my thoughts in this empty space. :/ Recently, things started to screw up, like I always expected. Nothing lasts forever, 'forever' doesnt exist. I need to get that into my head, before I start being stupid making the same mistakes all over again. For 17yrs of my life, I thought I finally found some of my true friends at work, who knew things ended up badly. Conflicts started to get into the way when two different parties had different perspectives and caused more misunderstandings. And like usual, I got caught in between both parties since they were all my friends. One side tried to pull me over, but I thought I shouldnt say anything much since I wasnt the direct person involved in their conflict. Who knew, now they just talked amongst themselves, leaving me alone. What's with all these? Who ever understand how I feel when all these keep happening over and over again. And now because of this guy, my bestfriend and I arent talking, though I tried my best to clear up the issue with her. Tell me, what to do when everything is only one way? Feeling so horrible at work everytime I see all my friends, I started to go for breaks alone and suffered from bad appetite. Started to keep everything to myself, lost motivation for work, I think Im going crazy soon. Then this day came, where one of the customers insulted and scolded me, when she didnt understand what I was telling her. I couldnt take it and broke down. Colleagues working that day felt really worried about me, they started hugging me. But still,  spent my 1hr break crying instead of eating, who knew I felt so horrible deep inside. Honestly speaking, I had thoughts of turning to something I used to hate. Kept forcing myself to not think of all these, and ended up crying almost every night before I fall asleep. Can things just get better somehow? Sighhh, its just me being really unlucky isnt it? If I wouldnt die stabbing my heart, I would because I want to stop all these feelings, because I cant continue being strong.
