depressed & need a tiny tiny bit of advice

I've lost so much weight. I'm 18 weeks. my body looks nothing like it did before. ive lost my butt and thighs, i have no baby bump, and I feel miserable. I feel ugly and frail. I want my thighs and butt again. my jeans hang.off of me 😔 I'm in a financial situation and I feel like a lot of pressure is on me and my partner is wanting me to get a second job, but not seeing where we could save a lot of money on phones and TV and such. it breaks my heart and I'm tired all the time. I feel useless. baby was moving all of last night and this morning and I've maybe gotten four hours of sleep. do I go out and try to be productive? or cook spaghetti and stay in and eat/hydrate/sleep?
