Need some help!

Hello!
I am 23 years old, single, and have been addicted to porn on/off for years (since 12). As of recently, in the last 2 years I have not been able to get an erection naturally, and only when I start to "play with myself" can I can just semi erections (scale from 1-10...about a 4) I also get no morning wood at all too. I used to get erections just by thinking about women or stimulating in the shower, but now I get nothing. In the last 2 years, I've developed an "edging" habit...while looking at pornography and cam sites with sexting for hours and ejaculating two to 3 times. Now, I have not gotten an erection in the last 2 years because of this habit.
So, I ask....have a permanently damaged myself? How do I regain sensitivity/stimulation that I once had? Is just abstinence for a while will cure this? Ah, it is causing me lots of depression, really needing advice. And Would going to a therapist help? (as I went to medical doctors and they told me I am healthy)

 

Thank you so much for welcoming me! I just joined this community a few days ago, I hope I can support and guidance to get better. I'll def be looking at other forums and techniques to get better. May I ask what does PMO mean? and after a long streak, did you get back to the way you were? and do you have any technique or just abstinence?

 

Oh, you currently do these problems too? It's tough. Uggh...driving me crazy. Considering I used to have normal erections only 2 years ago. I tried hard mode for 2 months (even had a wet dream...haven't had one in a long time) but then I relapsed a few weeks ago...now I am starting again...4 days in. I hope I can reagin me erections ina few months.
