Is it worth scraping and saving like this?

Dear friends, I need some help again. Those who have replied to my post know my position. I have tried to feel a bit confident after I started taking up voluntary work. I am trying hard not to get back into a state of depression, but I feel very much disheartened at times.

I followed some ladies suggestions here and tried to look for ways to earn something, but couldn't find much given my visa status.

Though I am going to volunteer work, but that is just twice a week or so. It keeps me occupied for some time. But I am unable to hold on to the phases of confidence and cheer and usually slip towards self-pity, depression. I don't know what to do to maintain some self-esteem.

Please suggest some ways I can keep myself from brooding and feeling depressed. I do not have any friends and it is not easy too for me to make any. I am too shy and introverted to feel confident to go out and make friends. My husband as usual ignores me.
