I can’t eat

For about 2 months I’ve been eating really little amounts. I feel hunger pains but no appetite. When I try to force myself to eat I feel nauseous after one or two bites. I’m really frustrated does anyone have anything to help? I’m afraid to go to a doctor because i dont know if it’s a small stupid problem..

More of a backstory:

I have depression I’ve been off meds for a couple of months and now am on a new med (I’ve been struggling with this before the med too) I just got off birth control for like 3 months. I feel not wanting to eat or have any cravings like I used to. I had braces witch really made me stop eating because it was painful they are off now. I feel It’s not a mental thing cuz I actually wanted to gain weight cuz I’m naturally skinny and always wanted to be bigger since like middle school lol..

Example of what I ate today:

Hunger pains in morning I tried to force myself to eat so I had a ensure high cal one

Then hours later a Swiss roll

Lastly try to force myself to eat again making pasta and only had like 3 bite before feeling full and nauseous

It’s gotten really bad 😕

Please no comments like “just got eat a hamburger” or anything like that I really am trying to eat and it’s really frustrating

I’ve also lost no weight during like 2 months of eating like this. Just a photo cuz I feel like I’m going to get comments of anorexia. 5’9 140lbs
