Silly spambot grrrr.
I've never had the injection, but the first time I had any sort of hormonal contraception it gave me all of the above, it was unreal! I reckon it contributed to a relationship breakdown and poor uni marks that semester.
I started to take the combined pill (ovranette) and it made me extremely anxious and quite paranoid. I was always on edge. On top of that my temper became totally explosive, which was odd because I'm normally quite laid back. If I wasn't crying, I was arguing. Nightmare. I totally changed, but it got better. :)
I came off that pill that Christmas (I'd started taking it in September) and my mood rocketed back to good. It was pretty extraordinary! So perhaps as time go by your body will adjust and get used to the new hormone levels? I don't know for sure, since I was on a daily pill.
Lately I started taking it again, this time I've had no problems at all! I'm also on 100mg sertraline daily, do you take any ADs?
I hope it gets better for you, I know how horrible hormonal moods can be!
Ps. I'm in Nottingham, we're hoping to have an East Midlands meet sometime soon so it would be awesome to see you there =) xx
