Well, as I always say, reading someone's life by the way they describe their fears is a lot like being a detective. A dependence on parental family points to the possibility that the person hasn't found a spouse nor has a well-paying job, which is usually a sign that a person's personality differs from their current outer shell (which creates a shy, awkward personality that almost no one finds attractive.) A dependence on a spousal family (wife and kids) shows that someone both holds pride in something they created and also holds a little (sometimes lost) pride in the natal sex that created that family, but also includes the notion that the person is afraid of divorce, finances, and loosing their children. Too much dependance on friends or a social circle shows that a person doesn't really have a supportive family and gets their emotional positivity from feeling loved by friends or the reasssurance someone may give them a place to stay if things get rough, and yet a fear of loosing those friends stems from how those friends are most likely conservative and religious OR stylish and popular, meaning the person dependent on the friends is also religious and conservative OR (tries to be) stylish and popular. All in all, when a person is truly confident and happy with themselves, and healthy and financially well off, they don't tend to depend on anyone else, even spouses.
So basically, my advice, as always, is to create a wellness of the outer self and a wellness of the financial life, combined. Worrying about family and friends will be your least of worries when you feel very confident about who you are, and will be the least of your worries if you have a steady income and place to stay. A wellness of the outer self obviously means that one should look very close to the way they feel would make them confident. To most people, this is a physical combination of health (low weight, clean skin, healthy and controlled hair, pleasant body odor, groomed body hair), style (fashionable clothes, modern make-up, items that relate to persoality), and gender stature (facial traits that realistically represent your desired sex [may require surgery and FFS or FMS], the possibility of GRS, and possible gender vocal and gait training, ect ect.) However, depending on the person, they may take pride in a few flaws (plus models, drag queens, cross dressers, ect ect) and that is perfectly OK too as long as it makes the person truly happy without a cloud of doubts.
Now, with the discriminatory state of healthcare, hardly anyone can afford HRT, FFS, SRS, and Laser Treatments (Hair, Skin), and these four things are things that in various combinations usually are required for almost every Transperson to feel truly happy. This leaves few options: getting a job while you are your natal sex and at least getting through the day by taking at least a little pride in that natal sex and/or a certain ability or talent that you can accomplish in that natal sex AND/OR winning the lottery AND/OR plain out trying to explain things to family to see if they will financially support you AND/OR taking out a loan. Not much else you can really do from there. However, if you know the family is hateful and unsupportive, you do need a place to stay if things go sour above anything else. You have to live. You have to have some friends to stay with, or again, a well-paying job. And both those pretty much require finding something about yourself, natal sex or not, that you are indeed proud of. You have to have an inner personality beyond whatever you may look like. I know it's hard, because most people eek through life basing who they are off the ease of not being Trans and being attractive, but this gives you the chance to learn that the best personalities are sometimes based on inner talents, the talents of music, writing, art, hard work, sports, fashion, whatever you may love. So many Trans just seem to base so little on real world dreams and accomplishments - if there's anything you love that you can work toward and pride yourself on in natal mode that can translate over to Trans mode once you transition, find it and love it.
Basically, find it, love it, and make money off it (in the case of art, sports, fashion, whatever), or at least use your pride in that hobby or dream to help drive you through the workdays.
