I think you should've called them about 3 months ago... hmm.. kidding..

Let's take a look.. You should call them now, and here's why..
1. you feel depressed
2. it's been getting progressively worse
3. avoiding places
4. Job / exercise becoming more difficult
5. paranoid thoughts
6. questioning if you should be calling the doctor.. HUGE ADVICE FOR ANYONE IF YOU'RE QUESTIONING IF YOU SHOULD BE CALLING YOUR DOCTOR THEN IT'S TIME TO BE CALLING YOUR DOCTOR.. ANYONE THAT SAYS OTHERWISE IS FULL OF **** OR STUPID OR BOTH.
7. not taking meds consistently

Also you need to be discussing with your doctor about not being able to afford meds. There are programs such as Bridges to Access that help people with no insurance, in fact, all drug companies I believe offer programs. Many places ie. Walmart have 4.00 generics that might work for you..

Take care of yourself!!
