I was prescribed mirtazapine 3 weeks ago due to severe depression anxiety and panick attacks haven't been out the house for 12 weeks that's how bad I got anyway on the 4th day of the 30th helps me drift off nice to sleep. Depression has subsided a little but still having my anxiety. I take diazepam for this to get me through the day. How long does it take to go with anxiety? Also I have been getting really bad leg pain and cramps. Has anyone experienced this? My appetite come back a little I lost two stone in 5 weeks due to depression so hoping to get my appetite back as well. Any information or guidance would be grateful. Thank you. I'm 37 with 3 beautiful children. I just want to be my happy self again.
