Im a brother btw does anyone know what i should do? i eat fine, i do exercise aswell, im thinking of going to the doctor tho but i feel abit silly going to the doctor because i feel tired all the time, what do you think i should do?

this is a problem a lot of us exprience and it is because we are not in a proper and structured routine. You need to get yourself into a proper sleep pattern. The best time to sleep would be around 11 and this ensures that you can easily wake up for Fajr Salah and even Tahajjud.
You should try to sleep and wake up around the same time and your body would then adjust to this. Sleep is meant to be for nights and the day is meant to be for activity so make sure you don't spend the nights awake if there is no valid reason for it.
You should try and exercise at least 30-45 minutes a day. Best exercise is in the morning. Do some resistance training to. Limit your time watching TV and on the computer.
Eat a good breakfast. Rasulallah(Pbuh) used to have a honey in some warm water when he woke up. This cleans the stomach out and then a while later have some oats and porridge as this has slow release energy.
Have a light but filling lunch because if your lunch is too heavy then you will begin to feel lethargic in the afternoon and make sure you don't have a heavy evening meal. Don't ea later than 7pm.
Try not to eat fried and oily foods and avoid too much carbohydrate as this can tire you. Have a good and balanced diet not eating too much of a particular thing. Have plenty of fruit and vegtables of different varieties as our body needs a variety of vitamins, minerals and nutrients.
Structure your day properly and try to make a timetable or plan for yourself. You have tobe determined and think to yourself "I cannot waste anymore time like this for death can come at any second and i need to make the best of my time".
Shaythan will continue to try his best to slow your progress but be determined and do it. Feeling this lazy cannot be good for your worship as it would make you lazy in your ship to. If you have amasjid within 20 minute walk then you should try and walk there for all of your Salah or as many as you can go to. This would be reward for you aswell as exercise.
You need to discipline yourself otherwise you will waste huge amounts of time which you will never get back and who knows when death will come for life is so uncertain and we need to prepare before preperations are made for our funerals!
