How to deal with disappointment and guilt?
Not that important but I feel like I should preface this by saying I'm a young adult diagnosed with depression and social anxiety. Unfortunately I'm not in therapy (yet).
I don't have friends and I spend the majority of my time with my family. I have two older siblings who don't live at home anymore.
I don't really get out much (or at all) but I occasionally ask my siblings to do stuff with me because I never end up doing stuff on my own and I don't have anyone else to hang out with.
My sister has been regularly dealing with migraines since she was a teenager.
I feel so ridiculous and I'm going to sound like such an arsehole but because of her health issues she often cancels our plans and I can't help but feel disappointed and hurt.
I know it has nothing to do with me and she is in a lot of pain, which leads me to to feel extremely guilty, but I feel so betrayed every time she cancels a plan.
And it's probably not true but I feel like this only ever happens when she has plans with me. I feel like she doesn't care about me and my feelings, even though I know it's not true.
I know it's not her fault but I still blame her and am angry with her.
My issue probably lies somewhere else but I don't know how to deal with this disappointment and guilt. I already try not to expect anything but it never helps and I don't know how to get myself to be more compassionate.
I obviously never let it show when I'm talking to her (hopefully) but simply having those feelings and thoughts about her is not okay to me and I want to be a better person about it instead of being so self-centered and feeling like a victim.
Maybe someone has some advice for me.
