I feel useless

I literally hate my self and I hate that I do. I have a one year old and a baby on the way. I’m a stay at home mom and I have so much anxiety about everything. I literally can’t enjoy anything anymore. I can’t even talk to my husband about my problems because I just feel like I’m not good at words and last time I brought it up he just told me things will get better. I’m the only one who worries about everything in the house and I feel so lost. I feel as if everything would be better if I wasn’t here. I’m just so down and I have been feeling this way for awhile. Any tips on how to try to bette myself and what to put my energy in. I really want to start enjoying stuff again.
