Need to talk to someone about a depression relapse?

im not feeling very well. im 20 years old and i think im in the midst of a depression relapse, and i dont know what to do. i feel like im going nowhere, that this depression, the same kind that started at 13 is always going to be a part of me, now that im in college, and i just dont know if im "good enough" to make it this time. i spent the past couple of weeks procrastinating and extremely indecisive about my future career goals, and now that reality has hit me all of a sudden as my family and friends want to know what i plan on doing with my life, and its all my fault. im so lost. conveniently, i have a therapy appt on friday but im thinking about cancelling because of money issues..i'd love to go if it weren't so much money, you know? i really need help right now, i dont know what to do. thanks.
