My inlaws expects me to remember their birthdays, anniversary but when it's my birthday they never wish me. On my anniversary too they wish my husband and not me. I find them to be too egoist and I get irritated by their behaviour. What to do to not get stressed?

Learn to disconnect...it will take time but soon u will accept that there are some who value you, and some who don't. What matters are those who care about u. The rest don't want ur explanation. They want to see that u r stressed. So it's up to u. Eventually,when we give those who don't care less importance, they get confused and suddenly their attitude towards u changes. So learn to ignore these depressive emotions. Focus on those who care for u.
