I feel like i bother my best friend with my problems

My best friend is a guy I have started developing a crush on which is why I try to be more open with him now. He has deprssion so I feel he would understand things. Lately though hes been in a very bad place and so have I he says its not worse than otherwise but it obviously is maybe he just cant tell. When ive tried to begin telling him how I feel he said "I get that:/" or just sent a heart emoji and says he hopes I feel better then he didnt speak anymore. I feel a bit dissed because when he tells me hes not feeling great I always ask why and try to be supportive and tell him he can talk to me if he wants to talk and sometimes he does and sometimes he doesnt want to. Why isnt he giving me that same support? I dont doubt that he cares because hes always cared but ive never opened up to him like this before telling him how I honestly feel the closest ive gotten to that before is whn I needed a ride to therapy and my dad couldnt that time(I usually take the bus but it was 2020 pandemic was raging) I literally never ask friends for favors otherwise I like to not be a burden.Maybe I have just chosen a poor time to confide in him.I feel a bit bad I cant be more supportive to him right now and maybe he feels this too but I also feel dissed at the same time I recently tried supporting him even tho I feel shit too.
