Hello, I read your whole paragraph and I want to let you know that things aren’t as hopeless as they might seem to you right now! Before I give you some advice I can tell you that I understand you extremely well, I used to sh and had si and never thought I would get out of this darkness but I did and you can too.
Growing up is really hard and feeling this way occurs to more people your age than you might think. I am sorry to hear that your parents don’t take it seriously and don’t want to help you. That is not okay, especially since opening up to them is really hard. You should be very proud of yourself for doing so well in school. It doesn’t mean that you are not allowed to be unhappy. Often when you don’t feel great, you think you are being ungrateful just because on the surface nothing seems wrong. Clearly this belief is not very helpful, you are not ungrateful, no matter what your parents say. Also mental health in general seems to be a forbidden subject in your family which might make you feel like you are wrong. You are not. Mental health affects everyone and you are allowed, no you should talk about it. If you don’t want your parents to hear about your feelings and problems, I understand but please don’t let that stop you from getting help. Because this is unavoidable, you need help and that is okay. Reaching out here and saying you need help is a big step and I am very proud of you for doing so. I would suggest you do some research on where you can get some professional help for free. There are for sure some very good helplines and chats in your country that are available! I would also suggest you speak with your counsellor about it while telling him not to tell your parents. I am sure he will understand that you don’t want them to know.
Then there is you wanting to have friends. All I can say here is, I am sure people want to befriend you and I think it’s normal to want that and absolutely understandable. I am again sorry to hear that your parents don’t want you to have such connections, because you really deserve it. Try to reach out to classmates you think are kind, even if it might seem hard I am sure you will be successful !
I am sorry to hear what happened between you and your sister. It seems like this was very traumatic to you. You should again absolutely talk about this with someone professional. Believe me I believe you and they will too. There is nothing you need to be ashamed about. I know it probably feels hard to trust anyone at the moment, but most people are kinder than you think and want to help.
For your future: to me it looks like you are very strong, smart and talented therefore I am not concerned that you won’t make it. You will become a doctor and if your parents don’t support you, I am sure your teachers can help you with that. You can for sure also get financial help if you get good grades (which I am sure of), do some research about it and talk with your teachers about it. I am sure they are happy to help!
You don’t need to live up to anyone’s expectations, that is not your job. You are worth so much and absolutely wonderful. You can be incredibly proud of yourself. I think talking with other people than yours parents will do you some good. I would also suggest that you do the things you love if you are not studying. Like me for example I love art and I like to draw it helped me to stop hurting myself.
I wish you all the best and send you lots of love ❤️
