Anxiety that my Perineal abscess and fistula is a sign of cancer. I can’t sleep now.

26F and I had a perineal abscess a year ago, 6 months later I had another one and they found a fistula, so put a seton in, then another 6 months goes by and another abscess formed, so I now have another seton in. I strain ALOT, I have adhd so do neglect my health. I am very slim, but these past 5 months I have a stressful job, where I work some days 16 hours and others I’m so tired and unmotivated that I don’t work much. I have been eating an awful diet since my job. I am vegan and have been for 5 years. My breakfast is ok, lunch I skip or is relatively healthy. However, I neglect dinner and instead have vegan ice cream or crisps. I forget to drink water. I used to exercise 5x a week and watch my protein intake and eat healthy, since my job that I love btw, I’ve had no time to exercise or eat properly. I don’t drink much alcohol and never smoked, never done drugs and don’t vape. I do take adhd meds. However, I think irrespective of this it would’ve come back anyway as I had it twice before I kinda lost myself. It’s so hard. Anyway, I’ve had signs from years ago of awful stomach pain that went a lot better from being vegan. I’ve suffered with hemmoroids since being about 17 and occasionally had to wipe for blood from my back passage (I don’t think it’s from my poop maybe from a tear). I do sit on toilets sometimes for hours cause of hyper focus and maybe it was an ocd thing, but every time I went to the toilet I would force myself to try and poop, I honestly don’t know why it was as if that was a routine from sitting on the toilet seat. Anyway, I had my abscess surgically drained for the 3rd time about 2 weeks ago. After draining, all was okay for the first week and a half but the past few days I’m in a lot of pain again and there’s a lump there again in the same spot (I know it may be tissue) and I’m still draining quite a bit. There’s also pain now inside my actual butt hole, which does hurt, especially when I poo or there’s pressure to my butt hole. Every single time I stand up I experience dizziness, not in the first second but after 5 seconds I get an awful wind of headrush. BTW nothing of this abscess pain is unbearable like it was when the perineal abscess is there, but it still is painful. Im so worried it’s colon / rectal / anal cancer. I also had appendicitis about 2 years ago. I know everyone says stay away from Google etc, but I can’t avoid symptoms, I need to do research. Is this pain now just from my abscess or is it likely to be cancer? I know the comments will say, “get it checked out”, which of course I am going to. However it’s Saturday, so I’m going to wait until Monday to go to the GP, so I just need some reassurance and honest advice! The next steps were that I have an appointment in 4 months time. I know there’s not a lot of early symptoms of these cancers either! I also have been experiencing urine incontinence too.
