Wtf is wrong with me?

Hi guys if ANYONE could help me out or respond that would great so months ago I started getting extreme vulva itching. Eventually I went to the gp a couple weeks ago and she swabbed me and I got told I there was fungus detected (my discharge was never clumpy or weird it seemed the same) I took a pill (fluconzale) which only worked for around a day and then a week later I used a pessary. And for 3 days my symptoms completely cleared. I genuinely never felt happiness as much as when I realised this issue had been resolved however 2 days ago the itching slightly came back and I was so devastated. I thought maybe it was a stubborn fungal infection so I took another pessary yesterday. I woke up today still slightly itchy and looked at my vulva and it was slightly red and swollen. I don’t know what else to do at this point everytime I feel an itch I get a wave of depression. I also realised that I barely produce discharge and that I was a little dry so I used vaginal moisturisers which didn’t really help. What am I suppose to do? It’s gotten to the point that this has affected my mental health. I’m constantly paranoid and anxious that something severe is going on down there. Side note I’m 19 and a virgin. I just started uni and I just wanna live my life without this horrible situation. If anyone has advice or a similar experience PLEASE let me know.
