mashallah, it is soo amazing how you have changed and for that Allah loves you soo much. But because he loves you he will test you a lot too. This is your test, as long as you dont let other people get into your head and make you change yourself for the worst, you will pass with flying colours inshallah. But dont worry, tests in our lives always fluctuate, it may seem like your life is hell right now, but soon it will all be over. For me wearing a hijab was difficult at the start, but i dont let anyone tell me to change myself, because i know that im right in what im doing, and if i can keep it up for a few 50-60 years inshallah, then i can live in peace and happiness for the rest of eternity, and those who judged me and discriminated and hated me for what i did probably wont have the same fate. and i assure you that uni will be so much easier inshallah, depending on which one you go to, but many of them have a very large muslim population, and many societies you can join.
If you ever feel depressed and lonely, always turn to Allah, trust me, he has helped me soo much when i needed him, and Allah loves it when people turn to him in times of need. tasbih always help me calm down and remember my faith.
I will remember you in my dua, and if you ever need to speak to someone, feel free to message me.
