Bleeding gums, swollen throat, flu symptoms keep returning

Okay so this might be long, but I need some peace of mind. I'm an 18 year old girl, I weigh 105 lbs and I'm about 5'6". For the past 5 to 6 years I've been becoming ill with what seems like the flu. I would wake up with a sore throat, hardly any kind of warning I would just be sick one morning. I would also have chills, headache, fever, occasionally I would get a cough. I would be extremely fatigued with a headache and my body hurts. It sounds normal but each time I go in to the doctor they test me for strep and it comes back negative every time. Once he took blood and tested me for mono, he said the mono test came back negative but my blood count said otherwise so he diagnosed me with mono anyway and I was out of school for about a week and then I felt good enough to go back. This has been happening over and over again each time the doctor says it's a virus and he prescribes me antibiotics anyway "just in case." I also have Raynaud's phenomenon and this summer I couldn't even drink ice water without having an attack, and at one point after walking all day I had lost circulation in my feet to the point where my toes were purple. I went into the doctor and demanded he do something, he sent me to a heart doctor, took some blood, and took a chest xray. He never told me what he was testing for. He eventually prescribed me procardia and it has somewhat helped with the raynaud's attacks. In August of this year I became sick again with the flu like symptoms and about three weeks ago I became sick with these same symptoms again for the third time within six months. I went to the doctor and yet again a negative strep test both times, and both times he prescribed me some antibiotics and I took them. I stopped taking them mid dose this time because I thought it was pointless, but when I started coughing again I started up with the antibiotics. I just finished them about 4 days ago and am already getting a sore throat. There is a bump under the right side of my jaw just below my ear that hurts to touch. My right ear and rights side of my throat are sore. I am still fatigued, my body hurts everywhere and my muscles are burning. This year I've had almost no appetite and have lost about 10 lbs. When I stopped taking the antibiotics a few weeks ago I noticed a rash that looked kind of like chicken pox all over my back and stomach and on my forearms. I have taken amoxacillin a bunch of times so I don't think it was an allergic reaction. This week I also noticed a rash that looks like dry skin on my wrist and hand, but it's not elevated. Another thing that I don't think is associated but has been bothersome is my gums have been bleeding a lot, not when I brush my teeth even..sometimes it happens when I'm just sitting in class. I'm looking for some peace of mind or an answer, because my doctor thinks I'm continually getting viruses and diagnoses me with mono etc.

The medications I am on:
Procardia for Raynaud's
BeYaz Birth Control
Claravis-Accutane
I've also been taking benedryl everynight since I got sick a few weeks ago.

any answers would help!
