Hi Theresa,
Yes, mood swings are part of early recovery. You will get used to your emotions and how to handle them.
You said the meds are not working. I assume those are meds for depression? They usually take a couple of weeks to begin working. Has it been that long? If not, hang in there. If you really don't think the meds are working, you can always talk to your dr, because there are many other options for medication for depression.
Don't think that you will have to live in the darkness indefintely. You can do this!
