Should I re-test for HIV or focus on anxiety issues?

Hi all,
Little background on my situation. I am a 25 year old male living in South West England.
March 2017 I had unprotected sex a couple of times (stupid I know) and 3 weeks later I got sick for just over a week - sweating, fevers etc all the cold/flu symptoms and canker sores. I thought nothing of it as I work hard and spend a lot of time in the office so just put it down to being run down and stress. I got sick again a couple months later too but only for a few days.
In September 2017 I had a chest infection for a month and had two courses of antibiotics. I put this down to just returning from a festival where I indulged a bit too much in the alcohol and cigarettes and slept only a couple of hours a night. I also had severe pain in my groins which was worse with movement which I put down to playing football (soccer) 4 times a week.
My anxiety really started when one of my colleagues mentioned that I get ill a lot and always seem run down so I stupidly googled “why am I ill all the time” and went on a few symptom checkers which consequently led me to believe that I had contracted HIV.
I then had possibly the worst week of my life stressing about HIV. I sweated all day and woke up in pools of sweat if I managed to get any sleep at all, physically shook while sitting at my desk and just felt horrendously sick.
I had a HIV Antibody/Antigen rapid test done at a private clinic here in England in October. I believe this was a fourth gen test and I was told it was the most advanced test possible.

After 20 mins the doctor stood me up and told me to look at the lines on the test and told me that the result was negative (I can’t remember what the lines looked like). I was so relieved at first but I’m now back to worrying so much I can barely function.

I have had muscle and joint pains for the past 6 weeks, I’ve currently got the biggest canker sore I’ve ever had at the back of my mouth, about half an inch in diameter which has been there for two weeks, I’ve had headaches and am fatigued a lot, I have night sweats and to top it all off my girlfriend has muscle aches and diarrhoea.

I should mention that I have just returned from 6 months travelling Thailand, Cambodia, Vietnam, Laos, Bali.

My question is really whether I should get another test done or trust the initial test and seek professional mental help. I’m really a mess at the moment but my family doctor had told me not to re-test.

Thank you so much in advance for any contributions, I can see that these forums help a lot of people.

You provided the answer. "trust the initial test and seek professional mental help".
You don't have any medical training so it is unrealistic to distrust the science of the test, guess that you have hIV, self diagnose that you are experiencing symptoms that could be HIV, then conclude that you have proven you have HIV. You have proven nothing but the test has proven you are negative.
If you are still worried then seek therapy to try to end this illogical pain in which case you could live a happy life.

Thank you for the reassuring words. I’m stupidly thinking “what if the doctor read the test wrong” or “what if I am the 1 or 2 in a thousand that get a false negative” even though I had the test 7 months after possible exposure. It’s so hard to think rationally when you have this in your head but I’ll try my hardest!

You can get E Coli from a burger, but you don't test after every meal or do cancer imaging daily, so consider that your priorities are misplaced by fearing HIV.
