I don’t know what to do anymore i have this feeling that I’m so behind in life.

I don’t know who to talk to, i just need to vent. I don’t even know where to start. Maybe that lately Ive been feeling sad and anxious. I don’t sleep well, sometimes when i do i have nightmares. Sometimes I’m so anxious that my stomach hurts, and sometimes to forget about the stress i don’t eat, so i can focus on something else instead of feeling anxious. Besides that I just feel so damn unattractive, undesirable, unloved that it tends to make me even more sad. Feeling like this just haunts me, i have this feeling that I’m so behind in life.
