Ongoing pain and discomfort. Of life.

I'm a 26-year-old grappling with ongoing tummy issues for the past two months. Symptoms include persistent discomfort from the lower abdomen to the anus, a lingering daily pain, constant fatigue, a lack of hunger resulting in slight weight loss, and mental distress. Over the two months, symptoms have evolved from difficulty passing stools and irregular bowel movements (up to four times a day) to a burning sensation in the anus. Initial experiences included nausea, vomiting, and constant burping, which have somewhat diminished. The shape of stools has also changed, though not as drastically as in the initial period. I had history of gastritis around 4 years back. Seeking medical advice is now under consideration due to the persistent pain and changing symptoms which affected my quality of life.
