Hi Gogs - hug from me too. It is tough with the pain and fatigue, and coming to terms with having RA for life needs a lot of time and probably quite a few tears too - hopefully it will get easier as you learn how to pace yourself and your meds will make a difference to the level of pain - there is light at the end of the tunnel. Naomi is totally right about talking to your GP for help with persistent low mood - we might not like taking even more pills, but they can help.
Other people can be a bit insensitive at times - even when they mean well, they can say and do stuff that feels bad. Try to let these things slide over you and if something upsets you, try to walk away and find a bit of peaceful space to calm you. I've always found that going to bed and having a sleep helps me to recharge my batteries, but you'll find what suits you best. Being sad or angry is OK, in fact I think it's necessary to go through that before you can really come to terms with the illness.
Take good care of yourself - best wishes - Sylvia
