I cant help my husband.

My husband has had a lot of stress with starting his new career. Hes been taking it out on me a little by snapping at me quite often. Hes learning to manage his stress better but im very weak. I dont have good mental health, and instead of being able to help my husband im taking it all too personally.

Ive been failing at everything. Im disabled and a stay at home wife. I got really sick recently and got way behind on house stuff (he never says anything about it. Hes very understanding about me being sick and me getting behind). Its just little things like when I keep screwing up or when I dont read the situation write he snaps at me as his first reaction instead of trying to clarify.

Honestly I just keep screwing up and getting on his nerves. He is already stressed at work and I just keep bothering him at home too. I dont know what to do to help him. My lack of mental health is getting in the way and he deserves help.

How can I help him when I can't really help myself? I feel so pathetic. He should be able to have normal anger and mood swings without me taking it so personally.

Edit: im seeing a therapist via an app but we can barely afford it. I get antidepressants and they've been working but im still having issues.

Edit 2: id like to clarify that im a child of abuse. My husband is a great guy that does tend to have a little bit of a temper. Its my trauma that causes a lot of the issue.
