I just relapsed again

Hello guys,
as the title already said I relapsed. In recent weeks I am really struggling to not give into urges.
Every time I get an urge I come to the point of saying: "Screw it. I am just going to fap. Can't be that bad." I am not that guilty of it either but I really wish to get a better grip of life.
I am currently in university and I am doing okay. I am determined to become more successful though and porn is really in my way of achieving my goals.
I am really lazy because I am overstimulated and my momentum is really bad right now. I gained some weight again and let my workouts slip for the last couple of weeks. Second day with workout again. I also keep procrastinating on homework a lot.
Furthermore I started to really see other girls at my university and old friends as sexual objects and had really awkward sexual thoughts about them (disgusting fetish stuff that I don't want to talk about here). This really freaks me out and makes me feel even more uncomfortable being around them. I already have social anxiety that I am trying to "cure".

I now made a plan, where I scheduled my week roughly after how a day should look like for my sleep chronotype, Bear. Read into sleep chronotypes, it's really helpful.
Furthermore I will try to actively change habits. I used to get unproductive after lunch and then fap. Now I will go for a walk after lunch. I mostly got urges when I was procrastinating and stressing out, now I am going to start doing something more productive such as research on crypto and to motivate myself I am going to treat myself with a piece of chocolate after being productive for 15min.
I also made a plan for what to do when I get an urge:
1. Turn your focus on a productive task
2. Do push ups (at least 50, take short breaks if needed)
3. Take a cold shower
4. Muscle contraction exercise (first PC muscle, then stomach, chest and into your head)
5. Meditate

Anyways, I am really trying to get a new grip on my life. These changes and new habits are going to help me get on the tracks to a better life. I am going to be more productive in the future, actually follow my dreams and get stuff done. Wish me luck guys.
