Constipated for weeks

Hi all,

If you care to listen please do, im 17 and for the last 4 weeks around iv’e been constipated, once a week ill take a laxative to poop in which does work but i dont wanna carry on like that, my poop is sometimes hard sometimes soft, definitely have hemmoroides,  Im active always doing stuff, but i guess i may not drink water as much as i should or enough fiber possibly, but i definitely am eating, im getting no feel to poo ever, not bloated ever just a jelly belly. But what im saying is i get no feeling to poop and the only way ive been able to pass stool is through laxatives, i dont ever let myself go a week without passing so thats when i use the laxatives, i also bleed sometimes if the poo is hard but its bright red and not dark so i guess thats a better indication than being dark as it will just be a tear. I dont know honestly im just getting irritated now that im not getting any feel to go to the toilet and only being able to on a laxative. 

Thanks
