I'm a 17 year old female. Ive been feeling weird lately. Weak, sore, and feeling sick a lot ( No I am not pregnant) I've had stomach problems for a long time and have been taking ranididitine don't know how to spell it sorry. It's for acid reflux but I don't think that's what it is I also have been getting headaches. I don't know whats wrong and it's really hurting me I feel like giving up on everything sometimes I need to figure this out please help :(
