Hello I was good and healthy with my mind but since past 2 years I've gone through alot, did everything to not get into depression and anxiety again but I wasn't successful but this time I was able to handle it without any medication. seen alot in past 2 years but nowadays I'm not able to handle anxiety and depression sometimes I get panic also I feel shortness of breath. night are full of nightmares , I can't just take medication and sleep all day like I used to do before once until I got well , I'm the only bread earner of the family now and I just have to ignore my condition and have to keep working. Im worried that I don't get more unstable cuz I've to support my family I've talked to my few friends they all mbbs students and about to graduate this year they told me to consult a psychiatry as of I've all the symptoms of PTSD and I'm suffering with all this with 2 years and now I don't know what's going to help me.
