WeepingWillow23 - I know how you feel. I have the same problem with my husband and daughter, something goes wrong, I express my emotions to them sad / frustrated / angry... whatever it may be and the response is mostly the same - here she goes again! Itīs all going to fall apart, mark my words and so on and so forth.
When I questioned my husband about it he said that history had conditioned my family to seeing a negative emotion turning to anxiety, frustration, irritability and possible anger, withdrawn, sadness, depression. They knew that these situations / reactions / emotions were triggers for me to fall down a slippy slope. They were trying in their own way to help.
Your post title "Not 'allowed' to have negative feelings?? " made me chuckle as I feel that sooooo often. People want me to be "normal" but display a negative yet "normal" response that others frequently display makes me a monster? That is more harmful to me. That lack of trust from my nearest and dearest can really hurt and can sometimes lead to a rapid descent into a pit of dispair and depression cos I got it wrong again, didnīt try hard enough, was a total failure, no one understands me..... bed takes me, tears fall and they smugly say "I told you so".
As a parent I have to say that all kids and parents have different views on life and acceptable behaviour, even families with no hint of depression. As a parent I know I get on my daughters back for things she doesnīt deserve but itīs because I love her and want to protect her and she will always be my baby no matter how much she grows up and how old she gets, sheīs still my baby. Your parents have stood by you for 8 years, they sound like good people to me. I believe they are just scared, worried, concerned and wanting the best for you. I know that wont help right now, but maybe you could speak to them. Ask them to ask you a simple question, maybe "are you coping ok with the emotion of anger / disappointment / sadness or would you like some help?". Promise to be honest and let them help but ask them to respect your answer. If you are feeling like itīs knocked you a bit, let them in, let them help, theyīve proved their worth over the last 8 years. But if you are feeling ok about the emotion, ask them to lay off you and just experience the moment with you, sympathise with you then move on. Ask them to respect your achievements since last summer and review their reactions to situations the way you have.
I hope you manage to work things out and keep yourself balanced. I get the feeling of frustration you must get when the lecture comes from your parents as my husband does the same to me. Youīve been successful and they need time to adjust I think.
Just my thought and hope I donīt upset anyone with what I write....
