Help...Is it possible that i am in a severe situation? (Cancer?)

So my body is acting weirdly in the last one month... i surfed the internet and it ended up i have 10 out of the 18 cancer symptoms. I am afraid for my health, I have been going through excessive stress and anxiety lately and I have started to feel that I am destroying myself. I am the most healthy living person in my family (I am the one who eats the least sugar and who exercises regularly). I have also noticed that I lose a lot of hair in the shower but that is normal i believe. I just hope i havent got anything serious.

These are the symptoms I got:

Persistent cough

A change in bowel habits

Unexplained anemia (low blood count)

A change in urination (frequent urination)

Hoarseness

Unusual vaginal bleeding or discharge

Unexpected weight loss, night sweats, or fever

Continued itching in the anal or genital area

Nonhealing sores

Back pain, pelvic pain, bloating, or indigestion
