helping with anxiety and depression

About four years ago, I started to suffer real anxiety, so much so that I couldn't function at all, my husband was in hospital at the time, my brother in law had died and my friend had also died that week, It was also Christmas, the kids were all off school and it was snowing heavily. It was awful and I couldn't talk to anyone in my family as everyone was grieving. I remember just putting DVDs on constantly and trying to amuse the children.I went to the doctor who prescribed citralopram and offered a counselling service. I also kept thinking that I couldn't breathe and that I was literally going mad.  The anxiety did subside after about two weeks and haven't really had it since.  I went to the doctors two months ago as I was feeling so tired, more depressed than ever, even being on citralopram, and i was putting on loads of weight.  He sent me for a blood test and was diagnosed with an underactive thyroid!This had caused my depression, Im feeling so much better now Im on tablets, but Im also eating better and walking loads.
