Introvert people suffer a lot and sometimes they may have very few people to share which may apply to you. Sometimes if you share to wrong person ( if you are too privet) and exposed that hurts more and you will keep with yourself.

Find someone to share in person and you can trust too, or this is right way to be anonymous and see what they say.

You may like to do some yoga and meditation, may be financial situation are not favorable or school is bothering too.
Happy you step out and did the right thing.
