How do I overcome this sadness?

Lately things have been going from bad to worse. My dad lost his amazing job,my parents have been arguing a lot lately,I had a rough breakup from my boyfriend of 1 year,because of the stress I have horrible acne,I recently had an allergic reaction to this cream I used,and now I have this horrible rash on my back,The guy im pursuing now seems to have little interest in me,my family is on food stamps,its hard to realize that I can't go shopping like I used to since neither one of my parents have jobs, we can't take anymore frivolous trips to Jamaica like we have in the past,I only have one main best friend who works constantly, so i cant hang out with her. Im this sheltered girl who is used to 5 star things, and now i have to get used to "rough living". Im always sad and angry and i don't know what to do to make myself happy again...
