I have no idea what to do about this

I've been feeling constantly sick and tired no matter what and it gets worse when I eat so I hardly eat at all these days. I have bad anxiety depression and I understand these are symptoms of it but it's really worrying me. I know it isn't my heart everything came back clear and I am a little anemic but I take iron and it feels like nothing even works for me.

Anxiety and depression will make you feel this way. Have you seen a Dr for some treatment???

I'm going to see a therapist soon but the fact that I always feel sick no matter what just worries me despite the doctors always saying I'm okay

Could it be acid reflux?
