Attending therapy is going to be the best help for this kind of depression. What do you do in your daily life to lift your mood? I know its bloody hard to get motivated to do fun things, but with this kind of depression the more fun you have in your life the better you will feel.

I find volunteer work really rewarding, I havent done any for a while, but today I am planning to start it daily to see if it helps get me out of this funk. I also find being with animals can help regulate your mood, do you have access to any domestic pets? Does exercise help your mood at all? Its hard to do but for some people it can make them feel great. A nice walk with a dog, being mindful and enjoying your surroundings can give you a break from the depression. What about art? Does that interest you at all?

Honestly if this diagnosis fits better than it is brilliant that you have it, rather than being stuck with BP diagnosis. There is not as much stigma surrounding atypical depression, and it is far more common (especially among young people, I have no idea of your age). And it is also far more treatable.

I wish you goodluck and thankyou again for you help and support through my hard times. If there is anything I can do to help you, please let me know
