I thought my life was getting better, but seems I was wrong and it is getting even worse?

I (23F) Got a job two months ago after going through a cyber course and working before during and after it. But this job is the first one I felt I got for being me, not just my knowledge, which made me quite happy.

Even though it is an hour each way (ATLEAST) with public transportation, it does not bother me too much.

I get along with everyone, I am friendly, I help everyone and anyone (Even if it not my job, though my job does relate to support). I have more than a few work friends, I am happy with work over all but...

But I feel like I have to maintain it, and then I was advised by family members to not push it (I used to push it too far, but with help and support from professionals have learnt how to not do so. Learned how to avoid doing so BEFORE the new job) But then was told stopping by in their office (Each team or part of a team got a different office/room) once a day ruins productivity for them, or is just not normal, even though we do not talk for more than 10 minutes and it is usually less than an hour after everyone come in or a little before lunch (I do not eat lunch with the same people everyday, so most days I talk to those I know I will not eat lunch with that day.)

I live with my parents, in my country it is quite normal. I am the first born and the only one who live with my parents, as my brothers each got their programs they go to which living accommodations. When it is just my parents I get along with them quite fine, it is even nice sometimes to come home to them already being home and sit down and have a relaxed evening together.

But when my brothers come back home during the weekend/holidays, I just want to stay in my room the entire time.

They are mean, each in their own way, both very judgemental, competitive, arrogant, and many other things I am sure you can think of that relates or connects to anything I wrote above, and before you ask "What makes you think you are not?" Well, I am not arrogant, I admit my mistakes, willing to learn and am not competitive with people unless we agreed its a competition.

My brothers are mean to me, bully mean, takes their jokes on/with me too far and are just overall mean, judge me for the way I do things and get upset when it is not how they would do it. My parents claim to back me up but they really just tell my brothers it was not right and that is it, other than that they do not support me when it comes to them unleashing hell on me. (It is their house so I feel like they have more power than they give themselves.)

As for my friends out of work, I got 2, we meet from time to time, with the guy I used to meet every week but now that I am busy with the new job and had made a new investment, I don't have the funds and time to go out as often as we used to. The other one is a girl who I have been friends with since Highschool, and we stayed in contact this entire time, but meeting up with her is even harder as she is very busy and our times do not align too well.

I am not sure what to do, I feel useless and helpless, does anyone got any advice or wise words for me? Thank you for reading!
