I think i am depressed

Patient: I would like to know whether i should see a GP about depression. I am only 16 but i get constant back ache, head aches and i often sleep in even if i have had plenty of sleep, during the day i also tend to take naps to relieve the tiredness but it does not seem to work and i end up falling asleep at bad times. My appetite has dropped and i no longer feel interested in my hobbies nor do i want to take part in any activities i used to. I am unsure about the use of antidepressants as i have read there are many side effects to them what should i do?

Doctor:
