I can definitely see why you’re frustrated, upset, distraught and worse of all, hungry. However, it was your choice to work for your employer. It was your choice to move to SF to start a career in that industry. It was your choice to put debt on your credit card. Even more so, its your choice to have and pay for a cell phone. The cellphone bill could probably pay for some of your groceries. And if you need an emergency cell, there’s alternatives like pre-paid cellphones.
As cliche as it may sound, life isn’t fair. And in this case, you had the choice to change the way things are. Just like your colleagues, they made a choice to leave and move elsewhere in hope of a better more sustainable lifestyle.
I do wish you the best in your future endeavors, but realize life is defined by the choices you make and experiences that follow.
