Hi I'm Laura I'm 1.60 And My Weight Is 87

Hi I'm laura I'm 1.60 and my weight is 87 but as one dr said I have heavy bones too. I have many things to ask I don't know if my symptoms are for the same or are different things, I feel mucous dripping all the time in the back of my throat, I know i have sinusitis, I also get a burning sensation in the top of my stomach all the time before it used to be when i was hungry now it's always sometimes it goes for a little bit but it's almost always there, I also feel sometimes a burning sensation in my throat and a big knot but i guess that comes from the dripping, I also have regular headaches and I feel very sleepy all the time I thought it was because i wasn't sleeping more than 6 hours but in holidays i did it and still felt sleepy all the time, I also have somtimes in the year where i get diarrhea and last for months, also I don't know if this is a problem my period has almost always been irregular and by that i mean usually can take 3 to 5 months to get back, when i used contraceptives methods it becomes regular at the beginning but then disappear for months for me that is something normal but other women keep saying is not so I dont know, other thing I have is my throat sometimes feels to dry and it hurts a lot and drinking water doesn't seem to help much it's like if my throat was closing it's worse if i wanna cry it gets very tight and painfull also sometimes when I'm sleeping I wake up because I can't breath, I know are lots of things but it's a bit hard to go to the GP without having money and with so many questiond It would be very helpful to get something here thanks
