My main friend at the moment is causing me a lot of anxiety. It's not really her fault, it's more my expectations of her and what I want. I'm getting so worked up lately because I feel like she likes everyone else more than me, and whenever she's not talking to me I get really jealous that she's talking to other friends. I get annoyed to the point I start being a bit shitty to her, almost testing her to see how much she really cares. I just can't keep doing this though because eventually she'll get fed up with me because I'm too miserable or intense for her. I don't know what to do because I don't know what to do about feelings of anxiety and jealousy.
