Why aren’t I enough

I feel like I’ve been doing everything I possibly can. My work, I’ve been training the new people, I learned to drive all the special equipment, I’ve been covering every vacation and sick day my boss has taken in the past 2 years, but when it comes time to replace my boss I get passed over and my annual raise was half of what it could have been and I’m told I could have done more. My relationship; it’s been 5 years I’ve been there to support him and even bail him out of every money problem from all his expenses going back to school and wanting to start his own business and failing in his business and car repairs, I buy our groceries, I put thought into birthday gifts and holidays for him and his family. I cook our meals and do our laundry. In return i feel like he tries to spend as little time around me as possible we do separate holidays, we go on separate vacations, I tell him I’m having a bad day and all I get is a “that’s nice the weather is great today”. He hasn’t done or gotten me anything for birthday or Christmas or anniversary for 2 years. Then he comes home and starts drinking right away. My family; my dad excepts me to give everything to my little sister (I bought a new refrigerator and couches both got offered up to my sister before I even got them home “she needs them more”) My friends; only seem to call me up when they want something. I just started my own dog training business and a person I haven’t talked to in years called me up want me to train her dog and help her move for a “friends” discount of lunch and drinks to catch up. But what make it worse is I’m made out to be the bad guy when I tell someone no or that I want something different. I’m doing everything I can to be there and do everything and I miss something and I’m ungrateful to these people.
