I fully understand what you’re feeling, and no you’re not annoying or too much. Realise that sometimes people don’t reciprocate the feelings and treatment that we give them, and it hurts, really, but at the end of the day we only have two choices. One, get over it by telling them about it, or two, not voice it out to them and suffer alone. Try speaking to your friend about this, and if your friend seems to not be bothered and is not trying to make you seem better, maybe it’s time to think whether the friendship is actually worth it. Sending love!!
