How to cope when you're at the bottom without a ladder

So if anyone read my story of the updated events in my life, then you know i have questions to ask. I lost all of my supposed-to-be friends, i lost my boyfriend, i lost my apartment, i only make $9/hr at a part time job (no one can be full time at except the assistant manager, i get full time hours (barely!), i'm back at my parents house, and so far i can barely keep positive when people rub things in my face. How can a nice, humbled, selfish-less person keep their head up when so many things are weighing it down? And is it wrong that in my job search i turn jobs down because i know what i'm looking for, what i want, and how much i need to be making? alot of people keep saying i'm turning my nose up at jobs that they suggested but, why on earth would you suggest to "your friend" to work at a job they don't like, for less than what they were making? Example, a female friend (former) was telling me i should work at belk, even though it as part time. i said no thanks, i need something full time plus i need a higher pay than $10, she had a nerve to say that i have no right to be picky and that i should take the job because i really have no choice. Yet if i recall months earlier she was in the same position i was in when i was telling her about all these jobs that were hiring. She also had the nerve to say "well the job i am at it wasn't my first choice but i like it because its in a field of work that i like. Smh. So its okay for you to turn down jobs that you don't want and yet its a crime for me because i'm picky???? And finally, how does a person enjoy life and the situation that their in day by day? I truly am working on making my confessions and loving myself and encouraging myself, but its hard when you have no social life, no one to talk to, nothing to do, no money to support your endeavors or efforts and you're just stuck on a limb and a constant cry during prayer?
