Stress or something more?

So I’ve been having weird stomach pains.. whenever I wake up I feel nauseated. I’ve been feeling like this for maybe a week and a half. before it used to go away mid day.. but now my stomach just feels like it’s on the verge or grumbling like I’m hungry. I feel like I’m hungry all the time even if I just ate(Food isn’t that appealing anyway).. it’s really annoying more than painful. Though I do get sharp pains in my lower abdomen every once in a while.. My mom says it’s may be stress, and I do admit to feeling a bit sad lately but I hope it’s only that. I smoke weed regularly and have for awhile. Right now it really helps me feel tons better.. though it’s kinda of scary because I’ve never felt dependent on it, and I don’t yet.. but with this happening it feel possible. Does anyone know if I may be sick? or what this really is? or any good stress relievers? anything I could do to make myself feel better?

my immune system is pretty amazing.. though that doesn’t mean I’m not sick. Actually a few people I hang out with have been saying their stomachs have been giving them a hard time, maybe a stomach virus? but after all ..this does just sound like stress. This past week has been really kind of sad and lonely for me.

It sucks.

help :(
