Depression and anxiety has ruined my life

When I’m feeling depressed I usually distance myself from the people closest to me because I don’t want to burden them with my issues. I’ve never wanted to be that friend that always has something going on with her. I thought this rough patch would be over quickly but it’s almost 2 years and I don’t have friends anymore. I have poor body image and my anxiety makes it worse. I have no one to talk to and I can’t even see a therapist because I’m barely making enough for the basics. I feel so tired and trapped in my life, my body. Besides my immediate family, I literally don’t talk to anyone. I feel like like a failure because my classmates who I graduated with, are working and they all seem to be enjoying life, meanwhile I’m stuck doing a low wage job unrelated to my major, no social life, eating my depression away, gaining unnecessary weight, watching life pass me by and wishing my life would end. I can’t even reach out to people because I’m so ashamed of myself. I feel so dead on the inside on most days. I can’t remember the last time I was happy.
