Remedy for depression and anxiety

Q: I have been living with depression, stress and especially with social anxiety for a long time. I am starting to lose hope and don't know what to do. It has affected my life in such a negative way. My classmates graduated 3 years ago and I am struggling with this mental illness. My grades are affected. I start to shake whenever I am sitting with a group of people. I get anxious when I get an email from school. I can't taste the sweetness of Dunya. Always living in a dark place. I got a treatment from a psychiatrist for months and finished it but it still existed. I have been making dua's and try to pray on time at work or university. But nothing helps.

P.S. It started since I moved to Europe from Africa. I cant go back to my country because of a war. And Islam is not well practiced in the country I am living right now. No righteous friends except people who pull you to haraam things. I am surviving alone. It would be much appreciated if you give some advice or remedy?

Zakaat on a joint account

Q: My wife is a housewife and does not earn an income. I provide her with an allowance as well as contribute into a savings/investment account for her.

Questions:

1. Is she liable for zakaat on the money in her investment account (which I contribute towards) or am I?

2. If we have a joint savings account (in both our names), who is responsible for the zakaat in this account?

3. Since we are married in-community-of-property, would she be responsible to pay zakaat on any investments that are in my name?

Maintaining purdah when keeping family ties

Q: What is more important: segregation between men and women or keeping family ties?

I am asking because in my native place and family, people have almost completely left the rules of segregation between men and women. So, I'm afraid to visit my family members. I have been concerned about the rules of segregation that I stopped visiting my relatives for a long time. But because of this my relations with family members became really bad, which is another bad thing in Deen.

Also, in my current situation I can't survive alone. I need help from my family to survive. I cannot stop visiting them.

Also, many of them are not able to understand my stance on this issue. Many of them are getting a bad image of Islam when I give less importance to family relations. They seem to be going further away from Deen and Imaan because of me.

So, how should I balance?

I am a weak hearted person. I may not be able to boldly oppose the malpractices when I visit my family. Also, I can't bear to see their hearts broken because of me. I am also not able to convince them of our rules.

Now, I am feeling that I should give more importance to maintaing family ties. I am feeling that I should visit them even if I may unintentionally do some sin in the process. Is this the right way to proceed?

Trimming one’s hair with a machine after performing a second umrah

Q: After completing my first umrah, I removed all my hair using a zero trimmer. After 2-3 days, I performed a second umrah and again removed my hair using the same zero trimmer (though the hair was very little). I was in doubt in regard to whether I did the correct thing or not by using a zero trimmer. Is my second umrah valid as I used a zero trimmer?
