Help Me Please

I’m not to just diagnose myself with a disease but I think I’m depressed. I find myself often feeling alone even if I’m in a room full of people or with my significant other. I’m pretty much always sad and I can’t really explain why. I want to be left alone but when I’m alone I want someone with me. I don’t know who I am anymore, I don’t have any skills or talents, I barely have any friends and the friends I do have seem to overlook me when it’s time to do things. I just need help and I’m clueless on what I ned to do....

Help please

I didn’t know where to post ig it’s considered health (mental)
