Not an encouraging man

My husband who I love so dearly is just so negative sometimes, I normally don't post on any social media or anything about my relationship but I don't have anyone else to just vent to 😞. This may be a little long so bear with me if I start rambling lol but anyway, I've been married since I was 20, I'm 24 now and we've been together since we were 17, I've always had a job as long as we were together I worked in highschool too and when I finished I went to a trade school for massage therapy and graduated blah blah blah okay after a while I developed carpal tunnel and I just couldn't do those repetitive grinding hand motions anymore so since I was 22 I've been wanting to go back to school but for registered nursing and then I wanna become a certified nurse midwife. I pitched it to a couple friends of mine who agree that that would be perfect career for me...But my husband has always found a way to make me feel bad about going back to school, like all of my endeavors are a waste of time and he says I'll never be... that'll never happen etc. He says I'll just be costing us money and I'm too old now I'll be 30 when I finally get started all that kinda stuff....Now me I've suffered depression and recently diagnosed as bipolar disorder those kinds of attacks at my self esteem always made me shrink and I just dealt with it. Now though I've been trying to take back control of my life and he's at it again but now I am registered in school to start my classes on January and he keeps getting in my head and I just want him to be happy for me, be happy that I want to do something with my life and have a career instead of just working a job I don't even like or get any kind of joy out of making me more depressed. He always says he's supporting me and all that but he really wants me to not do it and hopes I'll just quit but I really won't this time. I just don't know why he can't be happy for me 😞.

Sorry this is long but thanks for taking the time to read my rant
