Constipation. Relieved from suffering.

Sir/madam I am suffering with constipation since 2013 at which I noticed . I did journey of 40km daily for a tenure of 6 years continuously because of education. I started searching about it in 2015  and consulted various doctors in my town and on that they just said it is because of tension and fibre less foods and suggested Cremaffin plus syrup and some tablets which I had at that time and stopped in 2018. One more thing I masterbate atleast 2 to 3 times a week since 2011 due to illiteracy at that age and I feel some weakness when I masterbate since  2018.Beyond all this,since today I take in fibre foods such as leafy and various vegetables including some fruits and huge content of water daily but the problem still exists which makes me frightened to take journey to anywhere. Please suggest some better option to get relieved from suffering.
