Welcome to the site.
Well you should not have stopped lovan abruptly like that because such cold turkey withdrawal increases the risk for development of distressing ssri withdrawal symptoms which include electric shock sensations in the brain , dizziness, nausea, vomiting , tremors, anxiety , restlessness, rebound of depression.
However having said this I must also acknowledge the fact that lovan ( fluoxetine) is the safest among it's ssri class as far as development of these withdrawal symptoms are concerned owing to it's longer half life which allows the body to adjust to the decreasing levels of the drug thus preventing withdrawal symptoms.
Also I must mention that these withdrawal symptoms if at all develop are temporary and subside on their own within few days.
So to summarize --
-- You are unlikely to develop withdrawal side effects / symptoms from abrupt / cold turkey withdrawal of lovan due to it's longer half life however if at all withdrawal symptoms develop , do not panic as they will subside within a few days on their own. But if at any point during the withdrawal syndrome you feel that you cannot manage it on your own and need some type of intervention then at that instance you restart yourself on 20 mg lovan and after 5-7 days start to taper down the dose of lovan by taking 20 mg dose every alternate day for 1 week followed by taking the same dose once in every 3rd day for another 1 week and then stopping the drug completely. This strategy should have been applied by you in the first place if you wanted to come off lovan but anyways this shall be applied now if the need arises.
You see if not lovan, then any other anti depressant needs to be started to control your depression and anxiety because they are not going to correct themselves and will continue to make your life miserable , so you can discuss some very good anti depressant options such as Zoloft (sertraline) or Lexapro (escitalopram) or Cymbalta ( duloxetine) and ask him to choose any one of them to manage your under lying depression and anxiety.
As far as you feeling super sick after stopping the lovan cold turkey well this can perhaps be an early sign of impending lovan withdrawal syndrome which shall subside on it's own after few days but you got to endure it until that happens or else you shall restart on 20 mg lovan and adopt a slower method of withdrawal next time.
I hope this helps.
Wish you all the best.
