Hi ruesia
I'm so sorry your husband doesn't understand.
I'm like you in that I have been depressed since my teens, and I still fall back down the black hole sometimes and have to claw my way out. I know how to do it, but it takes time. I up my meds, see my T more frequently, walk, and journal...similar to the strategies you use. I see my doctor and he hasn't suggested any different meds or any other approach, he seems to understand I need time, and keeps an eye on me. He is just a general practitioner with a lot of interest and experience, not a psychiatrist, though.
I think I would resent it if my partner expected things of me other than what I know works.
You don't say if you are on medication or seeing a T. I know without my meds I wouldn't have a hope. If you're not, is it because you have tried and not had success? Also, besides the T you saw with your husband, do you see a T, by yourself?
I think those things are worth persevering with until you find what works for you, because they can change your life for the better so drastically.
I can feel your frustration with your husband not understanding you, or trusting you to know what you need. But this is probably scary for him, he's worried about you and wants to help. He doesn't know what to do, so he keeps offering possible solutions (many men like to do that).
Our loved ones want us to be happy and well. To sit on their hands when we are not is a struggle. I hope you can reach an understanding with him, because you don't need more to worry about right now. Hugs
