Feeling a bit overwhelmed and depressed. Please help?

I’ve been having a lot going on, I’m moving from Washington to Florida (which is where I’m from) in a month for work ( I’m in the military) and although I’m happy about that , I’m just not happy where I am in my life. At work, some of the people feel like they can talk to me and treat me any type of way. Im a pretty quiet person and I stay to myself most of the time and I don't bother anyone and I would expect people to not bother me in return. Aside from work, I have a huge feeling that my dad doesn’t like talking to me. Like I even tried to call him yesterday, and he didn’t answer or call me back if he was busy at the time. It’s like I’m not worth talking to with him. And even my mom was telling me that he’s changed and she feels like he doesn’t love her anymore.
Lately I’ve been having thoughts of suicide and it’s hard for me to even talk about to anyone right now (except for on the internet) and I’m afraid that no one will care or that anyone would say that I’m “overreacting”. I’ve been trying to push through it and stay positive but it’s hard. And I don’t want anyone thinking that I’m looking for pity or attention. Any advice?
