How to overcome ED and PA?

As the title says, how do I overcome ED(Erectile Dysfunction) and PA(Performance Anxiety)? Is it reversible and can it be cured and we can have a baby like normal people?

I would be really grateful for Any/all tips. And if someone has gone through the same thing, how did you overcome this?

Little Background about us: 32M married. Wife is 30. We have been married for 3 years now and everything was fine. We had initially discussed that we will wait for 1-2 years before planning for a kid. Now even when we started trying, we could not do it every alternate days as we had to travel to my native for various reasons and it was a small house with 6 people(We still did it somehow in between 😅). But even then we never did it frequently. It was like once or twice a week.

Somehow my wife conceived in May and we were very happy. Everything was going well but in June she miscarried at 8 weeks 😭

After giving a gap of 3 months we started trying again. One fine day when we were supposed to do it, I could not get erection, for reasons unknown to us(Note: This had never happened in my initial two years). We thought it's nothing and left it at that. And second time immediately after that, the same thing happened. Again we were not concerned and left it. But this thing had somehow gotten into my mind. And the third time I went in with some doubt, "What if the same thing happens" or "what if we miss again today and we would have wasted 6 days" and many such other thoughts. And all my fears came true and I couldn't perform 😔 again.

This time we consulted an andrologist and he said it's common and mostly psychological and nothing to worry. He gave me a pill and told to take 2-3 hours before sex. He also told me to take just 4 tablets and by the time I reach 4th tablet, the issue would have been resolved. But it was just the beginning of my problems..

After this incident,y confidence had come down and this thing became a common occurrence. This started causing rift between me and my wife. She is still supportive but I cannot blame her.l, since she also has needs. And what hurts me the most is I'm not able to satisfy and at the same time running out of time for having a kid.

Both me and my wife are working.ine is a general shift and hers is morning shift (6AM to 3:30PM). And we werenever much into exercise or doing any kind of training or physical activity as such. But since we started trying for baby, we started going for walks in the evening. We have completely stopped eating junk food and Started eating healthy food, like eating soaked almonds, walnuts and raisins, eating seeds like sunflower , pumpkin etc. At least we are trying our maximum to do this(Because we miss some days in between)

Some personal information about me: I started mastrubation when I was in 8th. We had just gotten internet and cyber centers and once when we went to play games, me and my cousin brother got introduced to porn. Someone using the system before us, had not closed all the tabs. That got me hooked to porn and this continued till my 10th std.

But since I was put in hostel for 11th and 12th. I could not watch porn. But I continued my mastrubation. But the moment I came to Engineering, it all changed. I got smartphone, internet, freedom and whatnot. Started my porn again. I always used to watch porn and mastrubate everyday before going to sleep. This continued for many years and even after marriage I sometimes used to watch porn and mastrubate. Now I'm not sure, whether this habit of mine, watching porn and mastrubating, has done some kind of damage, both psychologically and physically, but I don't get aroused very easily now. Somehow I was managing my married life and this PA problem came up and messed everything.

Fellow brothers and friends, kindly provide some inputs as to how do I overcome this?
