Dear Tea Time,
Welcome to the forums and thank you for reaching out.
Taking that first step is usually the hardest thing, and I'm glad you've crossed that hurdle. Now that you're here, I hope you find it easier to talk about what's on your mind. Your feelings do suggest that you could do with some help and our forums can hopefully offer some support.
You've mentioned that you often feel down, angry or feel nothing. Your happy moments are often marked by guilt, which prevents you from being fully happy. Unfortunately you blame yourself for your situation and place that burden on yourself to fix this.
Reading what you've written, I wonder what do you think you have done that needs to be fixed. Also, why is this something you need to fix yourself, instead of having others support you? If you're comfortable, feel free to share your thoughts with us (and if you're not, it's fine - you can reflect on this privately as well).
In the meantime, I'd encourage you to browse our forums and see if you can relate to anything our other members have shared as well. It may help you understand what you're feeling more.
Kindly,
M
