Anxiety is worrying about something or obcessing over things, being nervous all the time, scared. Often you may not know why, but still you are. It appears that your's has resulted in your worry over the HIV. None of your symptoms are a result of HIV, but rather anxiety from worrying about it. Get tested to hopefully put your mind at ease. Anxiety can cause diarrhea, but not swollen lymph nodes. You may have caught a bug at the same time, but it sounds like nerves to me. Also, if you're alternating between constipation and diarrhea, it may be IBS. There are many causes for night sweats, you may want to see your doctor to rule out any other problems before assuming it's anxiety.
Take care...

You may have some depression rather than anxiety, but only a professional can diagnose you. If you feel lonely, sad, mood changes from sad to angry, feeling like there is no hope, no ambition, lack of interest in friends and activites you used to enjoy, then you may have some depression. It sounds like you're fine, you were panicky at first, but have settled down. Of course this will be on your mind, but you sound like you're dealing with it okay. We all get anxious, or down from time to time, it only becomes a problem when it interferes with your daily routine.
