You are in a v stressful situation without alot of support so you need to use all the tools at your disposal to cope.When you are struggling AD's are certainly worth considering. My experience with them has been generally good although I think people react differently to various pills. You need to be under good medical supervision with a doctor you trust.
As for AD's being addictive there are different views on this. Mine is that your body and mind get used to a drug after some time and therefore withdrawal should be done slowly. Whether or not this means 'addiction' I don't know but does it really matter? If you are at rock bottom do what you need to.
Others have mentioned counselling. Ideally yes it helps to talk to an extent but a big but. Its hard to get counselling free on NHS there are many private counsellors out there who of course charge. Don't mean to sound cynical but I saw one for several months spent loads realised we talked about the same things each week. In end I realised if anything it was making me worse but she thought i should continue to come. I decided to stop.
Hope things work out
