It's ok that you're feeling this way.

I also use d2 as an escape.

Hobbies are good. I like social group bicycle rides.

Touch some grass when you're able. Soak up some sunlight.

If you're getting to the point where you feel like you are disconnecting mentally, maybe try clearing yourself of the situation.
Create space, work on the relationship with your family and try a new hobby that will keep you busy. Honestly, most community colleges offers courses in cooking, carpentry, metal working and etc. (The cooking courses are fun!)

But ideally, you may want to talk to a counselor/therapist before making any big moves.

Hobbies are good yes but healing is better.

If you believe in God, I'll give you the same advice I give myself: pray and read scripture, you will be fine.
If you don't believe then aim for truth, dedication, responsability. Respect yourself and be a man.

Okay, here is my advice since ppl are pretty serious and helpful so far

1)Do not reach out to her for any reason. No email, no chat, no commenting on social media or even an emote. Do not ask the reason why she did X and such. It is completely irrelevant. Cheating is not always about you, it is most of the time the person's insecurity about the relationship etc.

2) It is natural to feel a sense of loss. A loss produces stronger emotion than a gain. However you must understand that nobody owns anyone. They are individuals with choices even if they break your social contract. The best approach is simply to walk away.

3) You must be 'complete' as a person without relying on others for meaning and emotional validation. If you project confidence and emotional stability, you may begin to recognize those same qualities in others. Avoid falling into “all women are like this” or “all X people are like that” thinking. The way we perceive others can sometimes reflect what we ourselves project into the world.

4) This is the most important step. Wait for people selling hephasto on ladder reset. Join that game and kill it.
