Ashamed of myself.. feel like a failure?

Well its been two months since i have graduated with a whopping 2.93 gpa in finance and management. I have been looking for jobs for almost a month and i have had a couple interviews but no luck. I feel like i have let my parents down. I first started off as pre-med and changed my major because i just wasnt smart enough. I would try so hard for a cl and still would get below average grades. Consequently changing my major didnt help.. i was still stuggling as a business major and got below average grades in several cles eventhough i studied day and night. And to make things worse my friends are all doing well. Some have got into medical school, pharmacy school, and graduate school. And me.. nothing. My parents always compare me to them and its just sad. I have not accomplished anything in life and i feel like im the prime example of someone sucking at life. I had all the opportunity in the world and i let my parents down and especially myself.
