Please get some help, even if your depression tells you it makes no sense. There is hope for you and you are not alone in this. There is nothing wrong with you and you are not an attention seeker, but please do what is best for you and seek support from a therapist or doctor.
Feeling guilty for being depressed because others have it worse only makes you feel worse. Depression is not a fault, it is a desease and it can be healed or at least helped.
Even if you don't think you have the energy, continue doing one step at a time. Don't give up.
Lots of hugs
