I am 20 years old. I was having some family problems so I was in high depression, anxiety, hypertension, suffering from PTSD and was suicidal. Due to these psychological issue I was also doing very high drug abuse. Now I am out of drugs and little bit happy too as some problem are resolved too. The main thing is I was soo good at sex 2 years back with a good size and very good stamina. But now I don't achieve erection to fullest and for a long time. Any tips suggestions comments and medication or natural treatment. Please help. I am not able to sleep. Its just I had indulged myself into activities so I get tired and get to sleep after struggling for it over bed for hours. Still level or stress depress and hypertension is too high.
