The beginning

Two weeks ago my life was as perfect as it had ever been, and if I'm honest, as perfect as it'll ever get to be. However, recently everything disintegrated, loneliness has overtaken my life and my plan has been unwillingly torn apart.
So, what do I do now?
It's difficult to come up with another journey when you've had to figure things out so many times before, sadly, my depression is leading me to believe my only option is through the 'light', shall we say.  It's only at times like these do you truly see who you matter to and what matters to you, which since I have already mentioned that I am consumed in loneliness, you can imagine I have very few people who care, if anyone at all.
I'm starting at the beginning of now, rather than the beginning of my life because it's now that's affecting me rather than my past, albeit we will no doubt get into that at some point.
So, currently I'm a 22 year old female, studying at university (although not attending thanks to anxiety), I work forty hours a week at a retail store, I'm 5'9 and brunette. Obviously, I cannot be objective on my appearance, but I'm overweight to say the least. It's funny really, if I was able to live in my imagination then everything would be perfect. It's reality that ruins me.
