It's been around a year and a half and I'm still lost

Around a year in a half ago my ex girlfriend left me and then about a month later my dad passed away due to liver failure and I haven't been the same since. Both events happened so close to eachother that I wasnt able to completely process my break up before I got the news that my dad was going into hospice and then passed a month later. My dad was already sick prior to this Constantly in and out of the hospital which had already taken a toll on me and my family. He as really special to me. He's the the only person I was able to open up to about my depression back in 2020. He always just wanted to see me thrive and right now I'm not thriving. im so lost. I'm always locked in my room. Hardly leave my house. Haven't really made any effort to meet new people or hangout with friends. I go to work and home and that's it. I'm not happy with the life im living. I want to improve my way of life but I have no motivation. I don't have suicidal thought but I'm always thinking to myself not being here anymore wouldn't be bad. I'm tired of feeling like this.
