To do or not to

Decisions,decisions,decisions
Its really hard making a decision especially when i have to choose between making the right decision and the logical one.Im about to decide on something and it has me thinking for days, thinking on what to do and not doing it because im filled with guilt or 'pity'.
This 'thing' might seem cruel to the naked eye but deep down i know that its the best decision ever.BUT,my emotions always gets the best of me, this is why sometimes i hate myself because i do things not because its the right thing but because i do it to please others. I need help seriously.
