Best hair extensions

So I went in for a haircut last night and just told her I wanted the bad ends off and we agreed on cutting of only an inch. I walked out with my hair 3.5 inches shorter than it was when I walked in and I HATE IT SO MUCH. There's no way I can style it so I don't hate it so I've decided I want to get extensions but I know nothing about extensions. My hair is thick and about shoulder length now. Help me please I feel so ugly and since I'm pregnant I've spent like 2 hours crying about how ugly I feel now 😭
