Happiest, one thing you should understand is that depression itself fills the brain with negativity and makes one feel like “no one cares, my life is hopeless, why bother, etc.” Many times you don’t get the true or real picture but one that is a little skewered. In a addition as others said, although people care, if you don’t tell them what kind of support you need from them, they are put in an awkward position because they don’t know how to help you other than to love you. People don’t know what to say and they can wind up saying stupid and hurtful things that can sound like they don’t care.
Please try and be specific. Call a friend when you need support or company and try to verbalize what you are feeling and what it is you need. Don’t expect them to know or guess.
