I feel that this is quite unfair to say. Not to OP specifically, but to anyone who uses escapism.
It can be very upsetting, even traumatic, if your only means of escaping the harshness of real life is being taken away from you. I am not saying these people shouldn't seek professional help. Just saying that it's pretty insensitive to say that a person with mental issues should just prioritise what appears to them as a more difficult and lengthy route (getting help) instead of the easier and shorter route (escapism). While it may look like a simple logical choice to an outsider, it's not to the person who is literally fighting a battle within themselves.
Ideally what OP should do is both seek professional help as well as find a form of escapism that doesn't aggravate their issues, which is why I suggested in my first post they should at least take a break if not outright quit multiplayer games. Escapism is a very important thing to everyone. We all need a space where we can relax, forget about problems, and just live in the moment to enjoy ourselves. Everyone needs time to reboot. The key is to not let the access to escapism make you neglect the vital things of real life.
And I don't disagree that OP getting banned may be good for them long-term, but short-term it's going to cause them a lot of grief. And that is normal.
I am bringing up what I said about this again because it seems to have mislead some people. The underlined and bolded section states that I really do not know if SE ever revoke bans or strikes on accounts. I suggested to OP that they could make an appeal at a far later date after proving they can play for a long time with good behaviour because I know of instances where this was successful in other games that are not run by SE. So there might be a chance that SE may do the same. Even if they do not now, perhaps they will in the future.
But these successful appeals were not a simple case of "hey I played for a year with no hiccups, can I get the strikes removed now?" or "what I did was three years ago when I was a stupid teenager, and I have grown up. Can I have my account back?". They were made very eloquently with great care. In order to be successful you need to very clearly show in the appeal that you have moved on and have become a better person. And of course not every appeal ends in the favour of the player. Only a small number do. These cases while not impossible, are exceptional.
