Pregnancy blues? πŸ˜“

Mere β€’ Mother of a 1 year old Daughter named Charlee :) she is half New Zealand/Tongan. 7 week premature baby doing very well
I'm 19 weeks currently and love this baby endlessly however, my pregnancy has been so hard. I've lost confidence in myself, my hair is falling out, skin is breaking out and I can't find any clothes what so ever. I don't take pride in how I look anymore and quite frankly id rather stay in my room then socialise.  I'm irratible all the time and people get on my nerves. Work is hard because it's physical and home life can be bad. My partner is great though 
Has anyone experienced something similar? ..
