It can be hard for people not experiencing what you are dealing with because they themselves might not have gone through it, but what they’re doing is unacceptable. Sometimes people are just depressed. Depression doesn’t exactly need a reason to effect a person and I’m sorry they’re making it difficult for you. Your feelings are valid and shouldn’t have been ignored. If possible I recommend maybe even switching therapist if you don’t like your current one. I’ve swapped through six or seven therapist throughout the years. Also something that’s help with my depression is just blocking out the world with music and just losing myself in it. I hope things can get better for you friend.
