Oxycodone, marijuana, or adderral addiction?

Hello, I am a physically healthy 20 year old college student. Since I was 18 years old I considered myself addicted to marijuana. I smoked atleast 2-5 times until recently where I smoke anywhere from 6-10 times a day and much more than I once used to consume.

Because of this addiction to marijuana I feel it makes it much more convienient to be high and do nothing until I have an assisgnment due then of which I take an adderral to cram or finish the assignment. This became routine last year and I have been doing it about 1-2 times a week depending on workload.

Also, this summer I came into contact with a percocet and oxycontin dealer. I take was taking it 2-3 times a week but have slowed to 1-2 as of late. I dont consider myself addicted, it is just something I used to wind down and relax for stressful days.

anyways my question is that as of late I have had very little to NO energy at all. Like i mean it is hard to get out of bed to get going. Can anyone lend me advice to what is causing this extreme sluggishness? what drug is it I am taking??
