Please I need your helpk

I'm a 40 year old man I'm suffering from Gerd for two years now and idk what to do. I've been having back pains, shoulder pains, cramps, excessive yawning, chest pain and sometimes in my groin. I lost a lot of weight. I use to weigh 150 lbs now I weigh 138. I work at the post office and made it even worse because I bend over and picking up packages or objects which I heard I wouldn't supposed to do that. One time my mom says I'm sickly because this disease and I cry. I try H2 blockers and PPIs and none of them work. I also faint like I'm going to die which I'm not so please tell me what can I do to make this disease go away for good. Thanks

I'm desperate b]

I went to a GI Doctor and did endospy done and I did have Gerd but not BE and I did some blood test and it came back normal
