Iam depressed

Non us img. I've all the stop starts for step 2 prep in 4 months. Did only 1000/4000 q. Not able to focus. Iam the eldest one in my family. The responsibility pressure, pressure to deliver it's taking a toll on me.There is something wrong with me. Iam starting to doubt myself.

I'm not doing enough. I am having pretty disturbing thoughts over a month or two but iam sure I will be able to control myself. But it's getting too much at times. It's too much. Sometimes all I want is isolation and study but iam unable to do it. Please help if anyone can.
