Well first of all CONGRATULATIONS on graduating from College!! That's quite an accomplishment! Good for you!

And secondly, I'm no stranger to depression. I've been depressed since I was a little child, and I'm now 63 yrs old. ACK!
My friend, you really need to see a therapist. You can't keep on like this. You're getting nowhere fast. I know -- people put a stigma on those who see therapists -- well, you'd be surprised at the number of people who go thru therapy now! Probably some of your friends have seen a therapist or counselor at one time or another.
Go see your doctor, and he can refer you to a good therapist. Or if YOU know of a good therapist, make an appointment and go see him. But the sooner the better my friend. You won't regret it.
I was in therapy for years, but I had a LOT of issues. So you wouldn't have to be in very long.

And I KNOW it would help.
I wish you the very best. Please take care & God bless. Hugs, Lee
