Congratulations! I hope you stand up for who you are and that you have a network around you supporting every step you take, regardless what direction.
Being selfish is considerate somewhat negative, especially among woman. Men are better when it comes to schedule their time with activities without even giving it a second thought. You should to. Make plans for your wellbeing, if that wellbeing is going to the gym, meeting friends, visit a spa, read a book, drink champagne alone in a bar or all of the above. What ever it might be.. just do it, not just once do it regularly.
You are not selfish it is called self love – enjoy it!
