Feeling like Iv had enough

Emma • Pregnant with baby number 4......
Tonight I started crying Iv been holding it in for some time now..... I just can't handle this pregnancy it's my fourth so you think I should be ok but the last one was 6 yrs ago and I don't no why but this time it's different since having my little boy I went to the gym a lot became healthy was never poorly and now I'm sick all day I'm tired I feel fat....
Iv just had enough I don't go out and see anyone coz I'm so sick and tired 
I want to feel like I used to feel NORMAL 
What is wrong with me I'm grateful for being pregnant of course but it's so bloody hard I'm only 10 weeks now 
Does anyone else feel the same as me or am I just selfish and stupid for being so upset 😓
