Feeling sad...

So I’ve been feeling lately that people can really care less about you and the things you go through internally. Someone please tell me if I am being a brat or if this is just life. I feel like the people who “love” you aren’t even in my corner like that in a deep way. I have friends that are more there for me than family. I grew up with a single mother and one younger brother who I never had a real relationship with. My mother lied to me and told me my father was dead. Years later I found out that wasn’t true and turned a little bitter. Now I am 23 and know my dad know only because I took the time to find him myself without any of her help. My mother was never really there for me emotionally and being that I never had a father growing up I was basically alone in that aspect. I learned to suck up my emotions and just deal with life ON MY OWN. I stayed in school have a car a good job about to graduate in may and pay all my bills by myself. I met a guy 3 years ago and we fell in love, a few things started to fall apart and a lot of it was my fault. We kind are taking time away from each other to figure things out but still talk and see each other occasionally. Now he isn’t even there for me emotionally. I guess I just always thought that when you love someone no matter what obstacles you go through especially for 3 years you’d still be there emotionally even if things are my fault. I opened up to him and told him about my depression and even told him how I had suicidal thoughts he never asked me how I was doing or why I was having the thought. He told me I was throwing a pitty party and he needs time to gather his emotions too for himself. He was the ONE person who I thought would always get me. And the one time I do open up it goes like this. I really do only have myself. Am I actually making a pity party for myself or thinking about this too much?
