>>1 I suggest talking to a career counsellor or an academic advisor. You know what you like to do, that's already half the battle won right there! A career counsellor can take those likes, skills, and interests and give you your possible options. If you're going to university you can always change your major, lots of people to it and it's nothing to be ashamed of and neither is being indecisive. However you should absolutely not give up because it's easier. Life decisions are hard and you have to figure things out for yourself sometimes and it can get hard but just keep working on it and you'll find an answer. Don't get discouraged.
I can understand your family issues too, my mom got diagnosed with Graves Disease and her doctor told her that it may have been triggered by stress, she then gets it into her head that it's my fault for stressing her out and making her sick. She also isn't proud of me, or at least she doesn't show it.
What I suggest doing is telling your mom that you're going to school and you're working on your future and she shouldn't worry so much. Or something like that. Remember to stay calm and try not to argue, even if the things she says bother you. Her suggestions are also really good ideas and you should consider them, she isn't being unreasonable when she tells you to take a year off to work things out, a lot of people do that and again it's nothing to be ashamed of, if anything it'll help you get your mind on track. Shadowing a doctor is also a good idea if you don't know what you want to do. Being a doctor is relatively different than it originally sounds, depending on the field, you may even end up liking it.
Being openminded is a good thing to work on, try out new things and see what you like.
I hope that this helps :3
