Its ok to cry, its not stupid at all. Its not a sign of weakness either, just a sign of pain or hurt and its alright to feel hurt. Understand its normal, I cry all the time too (whether I'm happy, sad, angry, calm doesn't matter I still cry). Remember if you don't like something, you can always change it, it might take a lot of work but its still possible.
You are strong, you will get somewhere in life, just believe in yourself. I wish you all the best, and like I've said before just message me if you want to talk.
You are such a wonderful person, don't forget that :)
