I'm in serious pain and trouble. Need advice

Good day fellow fapstronauts ! I'm posting under this platform because I'm seeing myself in danger and I need advice.
I'm a porn and mustabation addict for over 13-years. I embark on Nofaf in hardmode and I'm currently in my 4th month (specifically 112 days) rebooting. During my journey, I managed to make it to 102 days free from PMO, except wet dreams. On my 102 day, I was romancing my girlfriend and while we engage ourselves in long kiss, I accidentally and uncontrollably orgasm out of my wish. Since then, I resume back to my hardmode reboot till date and I'm keeping away from my girlfriend to avoid her causing me relapse again.
My major problems I'm facing currently which are worst than the time I'm fapping are:
I'm very irritable, angry, mood swings and doing annoying things.
I'm facing serious anxiety, can't relate maturely with people, always alone and thinking negatively.
I'm feeling as if my heartbeat increase above normal and in my brain too, as if its turning.
And the worst of it is I break up with my loving girlfriend because it seems she no longer withstand my everyday problems, fight, anger, negative talk,......
My question is, are all these part of the rebooting processes or there is something wrong with me physically, psychologically or mentally ?
Is it the porn that affect my mentality and turns me like mad man ?
Please help me out.
