I have had periods since I was around 11 of being on anti depressants. I had a number of years in my 20s when I didn't and after an abusive relationship I went through a slightly provocative phase 
. I have remained single for several years now and seem to have lost interest.
I don't feel tearful and I function with work and being a mum and keeping the house in order but tend to avoid socialising a bit. I go through spells of not sleeping at all well, this has been an issue forever, my sleep has always been erratic. I either take hours and hours to get to sleep or fall asleep and wake up after a couple of hours. I sleep better if I don't have work the following day it is common for me only sleep 2-4 hours most nights. If I don't have work i can snooze till mid morning.
I get quite anxious usually in the evenings and get a few intrusive thoughts but I feel this is through loneliness as the symptoms go if I have a friend over. My question is what is normal or should I be medicated forever?! I have tried citropram and didn't sleep at all with it. I then tried fluxotine for months, I didn't feel as anxious but I didn't feel anything I felt numb and a bit zombie like. Any suggestions or advice would be appreciated.
