For the past 6 months I felt like a broom that could fall in either two directions

I could fall one way, and become a happy, succesfull man with a great future ahead of him. Or I could fall the other way and be trapped in addictions and social anxiety.

It's been a rough half year. August me and my gf of 5 years broke up. Part of it was because of my porn use, although she didn't admit it. Then hell broke loose when I realised I had no friends, no love life, no hobbies, was slightly overweight and addicted to increasingly shamefull pornography.

While getting over my previous relationship I had to work hard on myself. Obviously I started with nofap and gained the confidence to do other things.
I got back my old hobbies just to have something to talk about with people. I added lifting as a hobby, and lost weight quite quickly. Then I started getting closer to people around me, even considering them friends. Then I got promoted at my job, and managed to buy my own apartment at just 22.

But the feeling of falling either way is still the same. With the succesfull life just inches away I still feel like if I give in to my old life all this will collapse in a moment's notice.

Even though so much has changed I am still a balancing broomstick. I am getting tired of being cautious. I want to enjoy where I brought myself. Has anyone shared this feeling? Did it ever go away?
