Finances ruining our relationship

I need advice this year my fiance started struggling financially nd its made things so hard me being younger than him nd in college my part time job mostly takes care of just me but ive had to help him with gas and food ect. This drought happened at the worst time we move into our first apartment in a couple of months nd almost everday im like have you found a new job or have yu saved? With my anxiety it so hard to sit back nd chill nd not worry which leads to arguments. We cant afford to go out anymore we havent got to enjoy the proposal i cant even be excited about a wedding. I try to be supportive and optimistic but idk what to do it just seems its hard to be broke and happy and stressing so much this young
