I really can't tell anyone my feelings?

For a very long time I kept my feelings to myself, but then--I woke up and realized that I had to share my feelings with someone. I choose my parents. Who knows why? They basically scold me and told me that I was dissapointing them. It has been a constant battle to get them to hear me and understand how I feel. I tried like a a zillion times, and now--Ialmost want to quit. But something inside me tells me to persevere. It just has been heartache after heartache, and I don't know anyone. I know why they scolded me. They thought that "my feelings" would interfere with my studies? So many a times have they told me that children don't appreciate and understnad their parents until they have become parents themselves. How could I? I mean when I needed emotional support, they were not there for me. I appreciate them, but how can I truly truly appreciate them when I know that as a parent I would be there for my kids's emotional needs. I still need that from them.
