here's some background: Im a student in uni, and I dont have any stable source of income at the moment. My parents give me an allowance of $10 a day, sometimes less because they forget and I'm too afraid to ask. 

Before I go out for meals with my friends, I ALWAYS check the menu prices of the place we're dining at. If the cheapest option exceeds $10, I would give an excuse, saying that I'm not free - no matter how much I want to hang out with them. When I do go out for meals, I subconsciously calculate the price I have to pay for every single meal, especially if my friend group choses to share an item. If the price exceeds my budget, I would refrain from eating and tell them that I'm full so that I dont have to pay for it.

Sometimes I get so stressed about money that I BREAK DOWN crying. Once my friends and I went to an expensive restaurant for a meal, which I was unaware of. After eating, we split the cost equally and the total bill for each of us summed up to be more than 3× the amount I was mentally prepared to pay. My heart started pounding, my head throbbed, and I broke out in cold sweat right as I saw the price. I tried to rationalise with myself that I could recover the amount in the future when I work, but my anxiety got the better of me and I broke down once I reached home. For days, I kept thinking of this and blamed myself constantly, crying every night until I couldnt feel anymore. 

I thought I could get over this feeling but it happened again recently. My friend group went out for another meal and I ate a meal at home prior to going out, so that I didnt need to eat and spend as much. I ate as little as I could, telling my friends not to order my share as I had already eaten. I didn't even touch some dishes as it did not appeal to me and I didnt want to pay for it. However, my friends decided to split the cost equally and I got hot flashes again and my head hurt so badly. I broke down again at the thought of over-spending and it affected my sleep, mood, and ability to focus.

I haven't told anyone how badly money is affecting my daily life and decisions and how mentally draining it is to constantly think about money, because I'm afraid of what they would think of me. I'm also very bad at setting boundaries as I'm a people-pleaser, which also affects other aspects of my life.

I really appreciate if anyone could help me/ give me advice because I'm at wits end and idk how long I can put up with this anymore... 

side note: I haven't been diagnosed with anything yet, but I'm willing to seek help if needed because I realise I can't keep living like this

thanks again to anyone who can help
