Finding Hope in the Gloom

I’m a 36-year-old man and lately I’ve been feeling really down and lonely. It’s been hard to shake this feeling of sadness and I don’t know how to move forward. I try to distract myself with work and hobbies, but the loneliness always creeps back in. I know I shouldn’t be ashamed to talk about it, but it’s hard to open up to friends and family. I want to feel happy and connected again. I want to find hope in the midst of this gloom. If anyone has been in a similar situation or has any advice, I would really appreciate it.
