27 m suffering from erectile dysfunction. Please healp

Here is my story please hear me out I started watching porn at 13…masturbating average 2-3 times a day. At 19 I got in into smoking weed and at 22 I started gyming. Working out made my libido boost up and at 23 I started taking preworkout also. I used to smoke up take my preworkout and hit my gym sessions. Post gym sessions first thing I used to do was masturbate to porn. I decided to quit preworkout at 25 because it started giving me severe anxiety, anger issues and sleep deprivation. But the problem starts here. The day I quit preworkout I faced ERECTILE DYSFUNCTION. Its been two years now. I went to a doctor and he did some tests and everything came out fine. I did regain my erections back a few times but those phases lasted only for a month maximum.

What I noticed is.

1. When I get into heavy weight lifting I start getting anxiety issues again (I did heavy lifting 6 times a week for 3 years). Recently i quit lifting for a month and all of my anxiety, sleep problems and anger issues disappeared and even started gaining my erection back a little and morning wood too. (Not fully though)

2. When I have an interaction with a real woman I get better quality erections rather than when I am watching porn. ( but still don’t get full erections especially if I am on heavy lifting)

3. The doctor prescribed me a medication called zaptra which made me sleep like a baby and he told me that the reason of my ed was that my parasympathetic nervous system wasn’t working properly. But i stopped it after a month.

4. I quit preworkout at 25 after two years of constant supplementation with protein powder etc. but from past two years I am natural. The thing I am worried about is that since I am from india there is 99% chance the supplements I took were fake and it has caused a damage somewhere which is irreparable.

Please suggest me something.
