Every day is painful

It's great that you're doing your best at work.
You made your own decision to commute, so you have no choice but to give up and do your best.
Regarding congestion when going to work, I think it's a good idea to avoid congestion by going to work early. If you keep going, little by little you'll gain physical strength for commuting. It's really exhausting until you get used to everything.

It's better not to compromise until you find a workplace or job that suits you.
Who do we need to refrain from in life?
You can't provide happiness to others without being happy yourself. (^'^)
Don't compromise and keep pursuing until you find a workplace that fits you.
The ability to change jobs is also a talent.
More than half of the people in the world are bound by their own mentality of caring about the workplace, the people around them, and people, and are unable to move.

A third time might not be appropriate either.
Still, look for a fourth chance.
Work is a life partner on the same level as your partner, so it's better if there are as few uncomfortable elements as possible.
If it doesn't work even if you do it 10 times, look at your own negative reactions, face up to the facts, and try to devise ways to refrain from internal negative reactions.
Zazen is not a special Buddhist practice; it is a path where you can get a heart where you can stay at ease no matter what you encounter in your life.
This is because no matter what kind of situation anyone is in, anytime, anywhere, there is no resistance, and the first thing is that they simply live in harmony with that.
Apart from likes and dislikes, it's just that no matter where people exist.
Even now, when I look at it, I just see characters like this, and there are only things like this. That means it's the same no matter where you are or in any situation.
Therefore, no matter where you are, zazen meditation is a path where you can cultivate the strength you need without problems.
If you watch Toyama's pages, videos, etc., and find the value of making your mind tough, flexible, and intelligent, your negative reactions will be cut in half no matter what it is.
First, please take care to live honestly with yourself, don't worry about other people's eyes, and live true to your true heart.

I read it.
You're very worried because you haven't changed jobs and you can't easily work the way you want at your new workplace. I don't know the details about you or your workplace, but I feel like I can somehow understand your feelings. I understand your feelings from the bottom of my heart.
Well... there are quite a few times when I'm glad I changed jobs, but things don't go well, and I get tired or have to go through a hard time.
I also used to work as an office worker, and since I changed jobs, I went to various places, but it wasn't easy for me to get used to it. There were times when it was very difficult because my job was quite different from what I was talking about in the interview, and there were places where relationships didn't go well easily. If you hold it to yourself, it will be extra difficult and it will be so hard that you won't be able to sleep, and you won't want to go.
If that happens, we will end up in a negative spiral.
So I think it's okay to just think of it as a place of work. One option is to do what you can to the extent you can and if things don't go well, you can't help it, or quit. If things don't go well and you've been having a hard time, you can split up and quit if it doesn't suit you and move to another place. You may be concerned about age, but I think it's okay to put yourself in an environment where you can work with peace of mind without being too particular about it. In any case, it won't stay the same for the rest of your life; you're just working temporarily, so don't wait too long and take a good rest.
I sincerely pray that you will be blessed with many wonderful encounters and relationships in the future and that you will be able to live a peaceful and fulfilling everyday life. And I will support you from the bottom of my heart.

That being said, it was my own decision. With the conditions and details of the job change, you thought you could do your best. I wonder if I misunderstood...

There are things you notice when you actually work, and the burden of commuting is probably used by many people depending on the flow of people and time of day.

It's been a while since I changed jobs, so I'm worried, and I'm still unfamiliar with commuting, so it's not unreasonable to get tired. You're probably used to commuting from your previous job.

I think they'll get used to it day by day this time too. Also, if you try to shift your time or it's one train earlier, you may be able to relax even when it's crowded. Depending on the vehicle, it may be vacant, and if the platform is a little far away, congestion may also be avoided. Why don't you devise time, routes, etc.

Getting used to everything makes you feel more relaxed. Great place to work. Let's find good points and make it rewarding.
