From the question you Posted, I consider 1st change or treatment that you need would be stress management and lifestyle management ( regular exercise, sleep and salt restriction).
2nd thing is I'm concerned about whether you measured BP at home accurately or not. Coz loose or tight cuff, both may show increased BP. Please check your BP at a hospital or clinic atleast once.
3rd get your
lipid profile, ECG ,2D echo and renal function tests to look for other causes. High cholesterol, long standing BP can change heart size and
kidney issues can also increase BP other than stress. If any issue among these are found we need to add another medicine along with telmesartan 40mg.
Next Steps
