Ever since i split with my partner i've not been the same, i'm not the happy bubbly person i used to be. i think i need anti depressants. ?

Antidepressants: MAY play a role in your adjustment to life the way it is now but you know the reason you are depressed. That is called "reactive depression" and normally lifts eventually, especially w/the help of some psychotherapy, which might be the better option. That can help you develop coping skill that can be useful throughout life. Peace and good health.
