Recieve a Summons

Hello,
I was served a summons this evening for Porfolio Recover Asso. I haven't paid this debt because first I was on disability then loss my job because I was on disability. Then went on unemployment because of lossing my job. I barley making ends meet. Porfolio recovery is not the only card I owe. I was bombarded with phone calls so I stopped answering the phone because I didnt have enough to pay all of them. I answer the phone to talk to them and they were yelling at me "How much do you have" we need $1200 another call come in wanting $800 I dont have the money. I am on unemployment living in the Bay Area. What can I do the summons state I need to respond in 30 days. I really don't want to file bankruptcy
