Life purpose/ change of career

It sounds like you have a lot going on and leaving your spouse is a massive change that I'd hesitate to recommend if you're not in danger. Especially if you have a young baby, hormones play into things a LOT (my sister used to hole that in the 4th trimester nothing you feel is correct). Talk to your husband and see what options you have. And talk to a therapist so you can work on your social anxiety so you're not afraid to go out. There are too many factors at play to do all of that at once. Fix yourself/work situations first then give it time before deciding whether to leave.

So sorry you have to go through all that. It’s tough.
Feel free to message me if you want to talk. Not sure where in the world u from, but i have fair amount of experience ( uk job careers and job market).

my daughter is 18 months, I tried speaking to my partner, but he hasn’t been supportive
When I voice my struggles he responds with that’s life, I talked about leaving my job, he was completely against it because of the financial strain, I asked if he can have our daughter every other Sunday so I can have the day to myself and his response is well can he have the alternative Sundays to himself, because he needs time too. His opinion is just to get on with it and roll with the punches, he’s become very dismissive and it’s hard not feeling heard.
Thank you, I’ve been thinking about getting a therapist for while, which I want to do, I think I’ve been hesitating because of the costs and actually having to speak to someone f2f because of the embarrassment and shame I feel internally, but I do think that’s a good next step to take.
